The DSP56001 is a member of Motorola’s family of HCMOS, low-power, general purpose Digital Signal Processors. The DSP56001 features 512 words of full speed, on-chip program RAM (PRAM) memory, two 256 word data RAMs, two preprogrammed data ROMs, and special on-chip bootstrap hardware to permit convenient loading of user programs into the program RAM. It is an off-the-shelf part since the program memory is user programmable. The core of the processor consists of three execution units operating in parallel — the data ALU, the address generation unit, and the program controller. The DSP56001 has MCU-style on-chip peripherals, program and data memory, as well as a memory expansion port. The MPU-style programming model and instruction set make writing efficient, compact code, straightforward.
