ASIP as compromise processor

Short answer

An ASIP combines programmability like a GPP with domain-optimized datapath and instructions like an SPP. It achieves higher performance, lower power, and smaller size than a GPP for its domain while retaining more flexibility and lower NRE than a fixed-function SPP.

How does an ASIP serve as a compromise between the general-purpose processor and the single-purpose processor?

A GPP is flexible but slower and costlier for a given task, while a single-purpose processor (SPP) is fastest and smallest but cannot be reprogrammed. An ASIP sits between them: it keeps a program memory and a programmable instruction set (like a GPP, so software can change) but its datapath and instructions are optimised for one application domain (like an SPP). It thus gives better performance, size and power than a GPP for its domain, and more flexibility and lower NRE than an SPP. Examples: DSP and microcontroller.
