ZSP540 - Highly Efficient
Quad-MAC DSP Core
O V E RV I E W
The ZSP540 processor core is a high-performance/power-efficient Quad-
MAC/Six-ALU implementation of the ZSP
®
G2 architecture. The ZSP540 utilizes a
16-bit architecture with extensive 32-bit capabilities and sets an unmatched
balance of performance/power/size and memory utilization efficiency. The
Z.Turbo feature provides the SOC designer with the option to extend the ZSP540
Instruction Set and the ability to add application-specific acceleration logic.
