Abstract

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.
