ASIP versus general purpose processor
Short answer
General-purpose processors use a generic instruction set and datapath for wide applications; ASIPs employ tailored instructions and a custom datapath optimized for a specific domain, yielding higher performance and lower power for that domain. Examples: GPP – Intel Core; ASIP – DSP, microcontroller.
How do general purpose processors differ from application specific instruction set processors (ASIPs)?
| Point | General-purpose processor (GPP) | ASIP |
|---|---|---|
| Target | Wide range of applications | A specific domain (signal processing, control, networking) |
| Instruction set | Generic, large | Specialised, tailored instructions (e.g. MAC) |
| Datapath | Standard ALU and registers | Custom datapath units for the domain |
| Performance | Average for any program | High for its domain |
| Power and cost | Higher power and cost for the same job | Lower for the intended task |
| Memory/peripherals | Mostly external | Often integrated on chip (ADC, timers) |
| Flexibility | Highest | Medium, limited to domain |
| Examples | Intel Core, ARM Cortex-A | DSP (TMS320), microcontroller (8051) |
