At present, SOC has two kinds of realization: SOC based on ASIC (Application Specific Integrated Circuit) and SOC based on programmable logic device (SOPC, System on a programmable chip). SOC based on ASIC has advantage at performance.

• 目前，SOC有两种实现形式：基于ASIC(Application Specific Integrated Circuit，专用集成电路)的SOC和基于可编程逻辑器件的SOC(SOPC，System on a programmable chip)。
