  • Patent number: 4509116
    Abstract: A special instruction processor, such as a floating point accelerator processor, that processes a special class of instructions. Each instruction identifies the number of operands to be processed as well as the number of data words required to be transferred for each operand. The central processing unit retrieves and decodes each instruction, and transfers the special instructions to the special instruction processor. Both processors decode the special instructions to determine the numbers of operands and data words to be transferred. The central processing unit retrieves the data words from memory and transmits them to the special instruction processor. The special instruction processor processes the instruction and signals the central processor when finished. The central processor then causes the special instruction processor to transmit the processed data back to the central instruction processor.
