Several new instructions were introduced in the Tiny RISC
instruction set for effectively controlling the MorphoSys
RC Array operations. These instructions enable data transfer
between main memory (SDRAM) and frame buffer, load configuration
from main memory into context memory, and control RC array
There are two categories of these instructions: DMA instructions
and RC instructions. The DMA instruction fields specify
load/store, memory address (indirect), number of bytes/contexts
to be transferred and frame buffer or context memory address.
The RC instruction fields specify address of context to
be executed, address of frame buffer (if RC needs to read/write
data) and broadcast mode (row/column).
