What Is An ASIP?


ASIP stands for “application-specific instruction-set processor” and simply means a processor which has been designed to be optimal for a particular application or domain. General-purpose versus application- or domain-specific processors Most processor cores to date have been general-purpose, which means that they have been designed to handle a wide range of applications with good average... » read more

Customizing An Existing RISC-V Processor


In a previous post, we considered how you could create an optimized ISA for a domain-specific processor core by profiling software and experimenting with adding/removing instructions. Using the open RISC-V ISA can be a great starting point for a processor that combines application-specific capabilities and access to portable software. The old-fashioned way to modify the instruction set wo... » read more

Domain-Specific Processors Enable More Than Moore


Last month was the 55th anniversary of Gordon Moore’s famous paper Cramming more components onto integrated circuits. He took a long-term view of the trends in integrated circuits being implemented using successively smaller feature sizes in silicon. Since that paper, integrated circuit developers have been relying on three of his predictions: The number of transistors per chip increas... » read more
