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., [[Application-specific integrated circuit|ASIC]], [[Field-programmable gate array|FPGA]], [[Complex programmable logic device|CPLD]]), including both high-end and commodity variations.<ref>http://www.dailycircuitry.com/2011/10/zet-soft-core-running-windows-30.html {{Webarchive|url=https://web.archive.org/web/20181013095941/http://www.dailycircuitry.com/2011/10/zet-soft-core-running-windows-30.html |date=2018-10-13 }}

Most systems, if they use a soft processor at all, only use a single soft processor. However, a few designers tile as many soft cores onto an FPGA as will fit.<ref>
