Editing System on a chip (section)

==== Processor cores ====
An SoC must have at least one [[processor core]], but typically an SoC has more than one core. Processor cores can be a [[microcontroller]], [[microprocessor]] (μP),<ref name="Furber ARM">{{Cite book|title=ARM system-on-chip architecture|last=Furber|first=Stephen B.|publisher=Addison-Wesley|year=2000|isbn=0-201-67519-6|location=Harlow, England|oclc=44267964}}</ref> [[digital signal processor]] (DSP) or [[application-specific instruction set processor]] (ASIP) core.<ref name=":1">{{Cite book|title=Pipelined Multiprocessor System-on-Chip for Multimedia|publisher=[[Springer-Verlag|Springer]]|year=2014|isbn=978-3-319-01113-4|oclc=869378184|author=Haris Javaid |author2=Sri Parameswaran }}</ref> ASIPs have [[Instruction set architecture|instruction sets]] that are customized for an [[application domain]] and designed to be more efficient than general-purpose instructions for a specific type of workload. Multiprocessor SoCs have more than one processor core by definition. The [[ARM architecture]] is a common choice for SoC processor cores because some ARM-architecture cores are [[Soft microprocessor|soft processor]]s specified as [[IP core]]s.<ref name="Furber ARM" />
