General purpose pin mapping for a general purpose application specific integrated circuit (ASIC)

Disclosed herein are various embodiments of an application specific integrated circuit (ASIC). The ASIC includes a plurality of functional units. Each functional unit may include a plurality of connections. The ASIC may also include a plurality of input and/or output pins configured to couple the ASIC to a circuit board. A programmable client may be associated with each pin, and each programmable client may be programmed to selectively connect the pin with which it is associated to one of the plurality of connections of one of the plurality of functional units. In various embodiments, the programmable client may be embodied as a multiplexer or a crossbar switch. Further, the programmable client may be programmed using any of boot firmware, hardware jumpers, and/or non-volatile programming registers.
