An application specific field programmable gate array (“ASFPGA”) includes at least two fixed functional units in a single IC chip. Depending upon a specific application for the ASFPGA, the fixed functional units may include one or more bus interfaces, event timers, an interrupt controller, a Direct Memory Access (“DMA”) controller, system timers, a real-time clock, a Random Access Memory (“RAM”), a clock synthesizer, a RAM Digital-to-Analog Converter (“DAC”), a display interface, a register file, a compressed image encoder/decoder (“CODEC”), or similar functional units. The ASFPGA also includes a general purpose field programmable gate array (“FPGA”). The FPGA is configurable to effect a specific digital logic circuit interconnection between fixed functional units. After the FPGA has been configured, the fixed functional units together with the FPGA perform all the functions specified for a particular ASIC design.
