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 execution.

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).
