FIELD-PROGRAMMABLE MODULE FOR INTERFACE BRIDGING AND INPUT/OUTPUT EXPANSION

摘要

One or more specialized field programmable modules (e.g. CPLD and FPGA blocks) and their programming interface are embedded into a processing system (e.g. a CPU, GPU, APU and/or chipset). The field programmable modules are in-system programmable, in contrast to the application specific integrated circuit (ASIC) modules that perform the core functions of the processing system. The programmable flexibility of the field programmable modules can have various benefits during different stages of the integrated circuit life cycle for the processing system, such as reconfigurable interface bridging and two-way I/O expansion.
