Frequently Asked Questions (FAQ)

NOTES:

• The MC68360 has an optional -dual- Ethernet capability. (MC68EN360)
• The 68349 has a 1 kbyte instruction cache or a 2k static ram. This memory has four partitions, each can be configured as cache or ram.
  
• The 68349 is known as "Dragon I" and is the most powerful 683xx.
• The serial channels in the MC68360 have a totally transparent mode which is useful since it can act as a ISDN controller.
  
• The HC16 series use the same modules as the 683xx series. The HC16 series use a CPU16 which is upwardly code-compatible with the HC11.

General Notes on the MC683xx Series:

• Availability of features is not necessarily mutually exclusive.
• CPU32 has a 16 bit external data bus. CPU32+ has a 32 bit data bus.
• The CPU32+(with cache) (as in the 68349) is referred to as a CPU030.
• A CPU030 is a CPU32+, a configurable instruction cache and a quad memory module. A CPU030 has performance comparable to a MC68030.
• Memory management is not supported in the MC68349.
• Chip Selects X - programmable CS pins to select external peripherals.
• ? - I do not have the data sheet for this device.
• PGA avail - Pin Grid Array. Easier to use as surface mount devices are difficult to solder. (but not impossible)
• These devices are very complicated. It is impossible to outline all the possible features. Refer to the appropriate data sheet.
• Some devices have built-in background debuggers. See data sheets.
• GPT = General Purpose Timer. See the appropriate data sheets.
• The 68HC16 series is not software compatible with the 68k series.
• The file apps.info from nyquist.ee.ualberta.ca contains a list of documents available for products such as 68302, 68360 and others.
• Technical Briefs for the MC68349(V), MC68322 and MC68356 are available in PCX format (zipped) via ftp from nyquist.ee.ualberta in the directory /pub/motorola/datasheets as files m68349.zip, m68322.zip and mc68356.zip and from AESOP either by phone or via Internet.

Peripheral Chips

There is a large offering of peripheral chips available from various manufacturers. The MC68230 PIT (Parallel Interface/Timer) and the MC68901 MFP (Multi-Function Peripheral) are common and very useful. 68K peripheral devices have a DTACK* output that signals acknowledgement of the bus cycle to the CPU - this is how the asynchronous bus functions in the 68k family.

Devices from other families can be used with some ingenuity in the interface. The multiplexed bus on other competitive products and the lack of the DTACK* acknowledgement signal are two issues. Generation of the DTACK* signal in these situations is simple.

8 and 16 bit Processors (HC16 series)

Motorola manufactures a wide range of 8 and 16 bit processors and controllers. The families are the 6800, 6801, 6805, 68HC05, 6809, 68HC11 and 68HC16 (16 bit) series. The HC16 series uses the CPU16 processor module which is upward compatible with the HC11. Many of these devices have built-in functions such as EPROM, analogue to digital convertors, PLLs and special drivers for stepper motors and LCD displays. Refer to the "Master Selection Guide" or SG166/D for more information. Information and free software is available on the Motorola BBS and most ftp sites. Dunfield Development Systems, Nepean Ontario, (613) 256-5820 or ddunfield@bix.com provides low cost compilers and emulators for these products.

See the MSA BBS under the Motorola BBS. Much of the information in this FAQ pertaining to Motorola resources, ftp sites and general information is also applicable to these processors. BR261/D outlines these product lines.

The 68HC11 Microcontroller FAQ by Russ Hersch (hersch@silicom.co.il) contains a listing of resource information about these processors. It is posted once a month to comp.robotics and other similar groups.
Mr. Hersch's 3 FAQs are archived at http://www.oritools.com/info or ftp://ftp.oritools.com/pub/misc/faq

The PowerPc FAQ from the newsgroup comp.sys.powerpc is also available from http:/www.oritools.com/info. It is written by Derek Noonburg of the USA.

My Intel 80386 clone (with 80387) 40 Mhz is 11049 Dhrystones. My original IBM XT 4.77 Mhz computer shows 300 Dhrystones, my made-in-Canada 286 10 Mhz clone @ 1889, a Cray EL92 @ 14,286 and a Sparcstation IPC @ 23613. Motorola claims a Macintosh Quadra (68040) runs 15-20% faster than a 50Mhz 80486. Spec numbers are most useful to measure computer systems and are inappropriate for CPUs so are not shown here. The Cray EL90 is a 1 gigaflop machine; a J916 peaks at 3.2 gigs @64 bits.

The new IBM PowerPC Embedded Processor PPC403GA may achieve 72k dhrystones. A PowerPC NT 3.51 running in a Msdos mode gave 13k and 83k in native mode. (these two not confirmed as accurate). A 486 50 Mhz returned around 20k.

PowerPc - MPC601, MPC603, MPC604 series.

The PowerPC series are Reduced Instruction Set Computers (RISC). They were developed by Motorola, IBM and Apple Computer. These processors are featured in Macintosh, Motorola, VMEbus and IBM computers. Neither the 601, 603 or the 604 seem to have a Program Counter or Stack Pointers in the MC680x0 sense. See Motorola's Web site at http://www.mot.com/SPS/PowerPC.

The 601 has three execution units: an Integer Unit (IU), a Branch Processing Unit (BPU) and a Floating Point Unit (FPU). It also has a MMU, RTC and a unified instruction and data cache with a separate L2 cache interface. It is a superscalar processor capable of processing 3 instructions per clock cycle. Motorola has never manufactured the 601. The sole world source is an IBM facility in Canada. Motorola is/will be making the 603, 604 and 620.

MPC601 Features: (the first PowerPC chip, used in current Apple desktops)

• Thirty-two 32 bit General Purpose Registers (GPR). (user level)
  
• Thirty-Two 64 bit Floating Point Registers (FPR). (user level)
  
• Six 32 bit Special Purpose Registers (SPR). (user level)
  
• Twenty-seven 32 bit Special Purpose Registers (SPR). (supervisor)
  
• Sixteen 32 bit Segment Registers (SR) (supervisor). (for MMU)

• Exception processing - uses vector offset table.
  
• 32 bit address bus - linear, not multiplexed or segmented.
  
• 64 bit data bus - not multiplexed (address bus not multiplexed).
  
• single-beat (1-8 bytes) and burst (32 bytes) data transfers.
  
• Two levels of privilege - Supervisor and User modes.

• Floating Point Unit (FPU) - supports all IEEE 754 data types.
  
• Memory Management Unit (MMU) - 52 bit virtual memory address.
  
• 32 Kbyte unified data and instruction cache - with bus snooping.
  
• 3.3 volt CMOS part - interfaces with TTL devices, 5.6 to 8.0 watts.
  
• 2.5 volt part - MPC601v

• 50, 66, 80 Mhz versions - 304 pin quad flat pack ceramic package.
  
• uses instruction set from the IBM RS6000 Workstation.
  
• the IBM RS/6000 Model 41 uses a 601 CPU @ 80 Mhz.
  
• RS6000 binaries will run on the 601 at full speed.
  
• The 601 data types are: integer (8/16/32 bits), floating point (32/64 bits)

1. Integer - compare, rotate, shift, computational and logical.
   
2. Floating Point - arithmetic, rounding, conversion, compare, *, +.
   
3. Load/store - integer and floating load, store and move.

4. Flow control - branching, trap, condition register logical.
   
5. Processor control - move to/from SPRs, MSR, sync memory accesses.
   
6. Memory control - control of caches, segment registers, lookaside.

The MPC604 will be available in early 1995. It is similar to the 601 with separate 16 Kbyte data and instruction caches (Harvard Architecture), separate data and instruction MMUs, 3 Integer Units and a Load/Store Unit. The SPECint and fp 92 values are 160 and 165 @100 mhz. A 100 Mhz 604 will have twice the performance of a 80 mhz 601 and 50% more at floating point.

The MPC620 (64 bit) will be used in the next generation Apple desktops. It has an embedded L2 cache and reportedly can perform six (6) instructions per clock cycle. It is aimed at high end desktops, Workgroup servers and similar machines. It has a SPECint rating of 200 @ 150 mhz. SPEC ratings are most valuable for systems and not processors so be careful with these.

Motorola's first RISC processors are the MC88100 (CPU and FPU) and the MC88200 (cache and MMU). They have separate address and data busses for instruction and data memory space. The PowerPC is not an upgrade of these parts. The 88100 family are presumably still available, but no longer appear to have a high profile in Motorola's present product matrix.

PowerPC Embedded Controllers

The IBM PPC403GA is a 32 bit processor rumoured to deliver 72k Dhrystones per second @ 33 Mhz. It has a DMA, DRAM and I/O controllers, two-way associative instruction and data caches, serial port and multiple timer facilities. It runs at 3.3 volts and interfaces with both 3.3 and 5 volt peripheral parts. It comes in a 160 pin PQFP package and is priced at $49 @ 25 Mhz for 1000 pieces. It is being sampled now with volume production expected by the end of 1994 and 33 Mhz version is expected in early 1995.

The Motorola MPC505 has a floating point unit, 4 kbytes static ram, 4 Kbytes instruction cache, 32 bit RISC processor, 32 x 32 bits general purpose register file and 32 x 64 bits FP register file. There are chip selects, a watchdog timer and various I/O ports. It comes in a 160 pin QFP package @25 Mhz and with a clock speed of 25 Mhz and uses a 3.3 volt power supply. It will be sampled in November 1994 and is initially priced at $75 for small quantities. A 144 pin package will be offered later. Volume pricing is expected to be $55 by 1995 and down to $25 by 1997.

Motorola and MIT are two syntaxes that exist for M68k assembler source code. As an example, the Motorola syntax is move.l xxx and the MIT syntax is movel xxx. These types of differences must be resolved before the source code can be compiled. This problem seems to be found in GCC code and appears to result from the inability of MIT's computer system to handle a ".". Rolf Spalink's file mit2mot.tar.gz converts from one syntax to the other. FTP from ftp://nyquist.ee.ualberta.ca/pub/motorola/portable or ftp://ftp.luth.se/pub/misc/motorola/m68k.

Motorola also made the ECB single board computer (MEX68KECB) that runs a MC68000 CPU with a wirewrap area for educational and development purposes. It uses the TUTOR monitor program which is a simple assembler and disassembler. They are no longer available but used units may exist. The TUTOR software is available (source code) from the Motorola BBS and ftp sites and can be used on home brew computers with some modification.

The documentation for the ECB is still available as MEX68KECB/D2 from the Literature Centre. It has schematics and TUTOR instructions.

Arnewsh Inc, Colorado, (303) 223-1616 / FAX: (303) 223-9573 makes a board similar to the ECB with a 5.25" floppy disk interface. It sells for US$375 with a 25% discount to universities and students. Arnewsh also make single board computers using the 68302 ($495), 68306 ($375) and the 68EN360 ($975, $1475 with the optional MC68EC040).

Mark Farnan in Australia, has developed a MC68332 microcontroller board that he would like to market. Its features include: 128 Kbyte Eprom, 64k or 256k Static RAM, Real Time Clock, 68681 DUART and an onboard monitor program. The board measures 3.75 x 6.25 inches and will sell for US$ 350 and will be available in 4 weeks. He has a 68340 board available now for the same price. For more information on either of these boards, Email Mark at mfarnan@mpx.com.au and he will send you a data sheet via Email.

Scott Mackenzie at the University of Guelph in Ontario, Canada has developed a MC68000 educational demonstration board that is available from URDA in Pittsburgh Pennsylvania, USA. It includes software and various i/o boards are available. The CPU board sells for around US$300 and i/o boards sell for $25 to $75. Scott has written support documentation including classroom experiments as well as a textbook om the 68000 and 8051. For more information: http://www.cis.uoguelph.ca/~mac/68KMB.html
