Programmable special purpose processor having simultaneous execution and instruction and data access

摘要: In a programmable special purpose processor for an input/output controller, data and moving instructions are respectively stored in instruction memories rather than one memory. While word is accessed from register to arithmetic unit response instruction, counter updated direct the subsequent be delivered prepare perform its next operation. At same time, memory address register, register. beginning of cycle, prepared execute instruction. Consequently, operating speed increased since words need not sequentially during cycle.
