A soft microprocessor (also called softcore microprocessor or a soft processor) is a microprocessor core that can be wholly implemented using logic synthesis. It can be implemented via different semiconductor devices containing programmable logic (e.g., Field-programmable gate array, CPLD).

Notable soft microprocessors include:

MicroBlaze
Nios II
