16 bits, Fixed-point Digital Signal Processor

The μPD77019-013 is a masked 16 bits fixed-point DSP (Digital Signal Processor) developed for digital signal processing with its demand for high speed and precision.

The μPD77019-013 internal ROM area is masked already by the void code to use as RAM based DSP without mask code ordering process. Also the μPD77019-013 can operate as simplified evaluate chip for as the μPD7701x family.

About mask ROM and mask option, there are following differences between the μPD77019-013 and μPD77019.

FEATURES

? FUNCTIONS

? Instruction cycle: 16.6 ns (MIN.)

Operation clock: 60 MHz

External clock: 15 MHz

? Dual load/store

? Hardware loop function

? Conditional execution

? Executes product-sum operation in one instruction cycle

? PROGRAMMING

? 16 bits ×16 bits + 40 bits →40 bits multiply accumulator

? 8 general registers (40 bits each)

? 8 ROM/RAM data pointer: each data memory area has 4 registers

? 10 source interrupts (external: 4, internal: 6)

? 3 operand instructions (example: R0 = R0 +R1L?R2L)
