ABSTRACT:
An application-specific integrated circuit (ASIC) for performing a selected one of a plurality of programmable functions on one or more input signals. The ASIC includes a plurality of component circuits (21-28), each for performing a predetermined component function (F.sub.1 -F.sub.8) on a signal supplied thereto, a plurality of component routers (31-36) for selectively coupling together the plurality of component circuits (21-28), and a control processor interface (40) for receiving control signals that control the plurality of component routers (31-36) such that selected component circuits (21-28) are coupled together in a manner by which the predetermined component functions (F.sub.1 -F.sub.8) of the selected component circuits are performed on the input signal in an order necessary to accomplish the selected one of the plurality of programmable functions. An application of the above-described circuit to a signal processing ASIC useful in stand-alone satellite modems is also disclosed.
