Encyclopedia
The multiprocessor System-on-Chip (MPSoC) is a system-on-a-chip
(SoC) which uses multiple processors (see multi-core), usually targeted for embedded applications. It is used by platforms that contain multiple, usually heterogeneous, processing elements with specific functionalities reflecting the need of the expected application domain, a memory hierarchy (often using scratchpad RAM
and DMA
) and I/O components. All these components are linked to each other by an on-chip interconnect. These architectures meet the performance needs of multimedia applications, telecommunication architectures, network security and other application domains while limiting the power consumption through the use of specialised processing elements and architecture.
System-on-a-chip
A system on a chip or system on chip is an integrated circuit that integrates all components of a computer or other electronic system into a single chip. It may contain digital, analog, mixed-signal, and often radio-frequency functions—all on a single chip substrate...
