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 combination. 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).
