摘要：A system for real-time digital signal processing employs a single- chipmicrocomputer device (10) having separate on-chip program ROM (14) and data RAM(15), with separate address and data paths for program and data. An external programaddress bus (RA) allows off-chip program fetch in an expansion mode, with the opcodereturned by an external data bus (D) . A bus interchange module (BIM) allows transferbetween the separate internal program and data busses (P-Bus and D-Bus) in specialcircumstances. The internal busses are 16-bit, while the ALU and accumulator (Acc) are 32-bit. A multiplier circuit (M) produces a single state 16×16 multiply function separate fromthe ALU, with 32- bit output to the ALU. One input to the ALU passes through a 0-to-15bit shifter (S) with sign extension.
