An '''application-specific instruction- set processor''' ('''ASIP''') is a component used in [[system-on-a-chip]] design. The [[instruction set]] of an ASIP is tailored to benefit a specific application. This specialization of the core provides a tradeoff between the flexibility of a general purpose [[Central processing unit|CPU]] and the performance of an [[Application-specific integrated circuit|ASIC]].

Some ASIPs have a configurable instruction set. Usually, these cores are divided into two parts: ''static'' logic which defines a minimum ISA (instruction-set architecture) and ''configurable'' logic which can be used to design new instructions. The configurable logic can be programmed either in the field in a similar fashion to an [[FPGA]] or during the chip synthesis.
