Z89320 Datasheet (Zilog.) - 16-BIT DSP DIGITAL SIGNAL PROCESSOR

Z89320, 16-BIT DSP DIGITAL SIGNAL PROCESSOR

The Z89320 is a second generation, 16-bit fractional, two’s complement CMOS Digital Signal Processor (DSP).

Most instructions, including multiply and accumulate, are accomplished in a single clock cycle.

The processor contains 1Kbyte of on-chip data RAM (two blocks of 256 16-bit words), 4K words of

Z89320 Features

* a 24-bit ALU, a 16x16 multiplier, a 24bit Accumulator and a shifter. Additionally, the processor contains a six-level stack, three vectored interrupts and two inputs for conditional program jumps. Each RAM block contains a set of three pointers which may be incremented or decremented automatically t
