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).
