Z89320 Datasheet | Zilog.

PRELIMINARY CUSTOMER PROCUREMENT SPECIFICATION 16-BIT DSP DIGITAL SIGNAL PROCESSOR GENERAL DESCRIPTION The Z89320 is a second generation, 16-bit fractional, two’s plement CMOS Digital Signal Processor (DSP). Most instructions, including multiply and accumulate, are acplished in a single clock cycle. The processor contains 1Kbyte of on-chip data RAM (two blocks of 256 16-bit words), 4K words of program ROM. Also, the processor 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...
