The first line should be used to generate a kernel for Sun-
3/160, Sun-3/260, Sun-4/260, Sun-4/370 and Sun-4/460 sys-
tems. The second line should be used to generate a kernel
for Sun-4/110 systems; and the last line should be used to
generate a kernel for Sun-4/330 systems.

AVAILABILITY
TAAC-1 can only be used in Sun VME-bus packages with 4 or
more full size (9U) slots.
DESCRIPTION
The taac interface supports the optional TAAC-1 Applications
Accelerator. This add-on device is composed of a very-
long-instruction-word computation engine, coupled with an
8MB memory array. This memory area can be used as a frame
buffer or as storage for large data sets.
the Sun-4/150 VME address space is limited to 28 bits. The
TAAC-1 must be reconfigured to work in this package. See
Configuration Procedures fro the TAAC-1 Application
Accelerator Board Set.
Programs can be downloaded for execution on the TAAC-1
directly, they can be executed by the host processor, or the
host processor and the TAAC-1 engine can be used in combina-
tion. See the TAAC-1 User's Guide for detailed information
on accessing the TAAC-1 from the host. This manual also
describes the C compiler, the programming tools, and the
support libraries for the TAAC-1.
Programs on the host processor gain access to the TAAC-1
registers and memory by using mmap(2).
