System processing unit extended with programmable logic for plurality of functions

Abstract

An integrated circuit including a main system processing unit which can be extended using a plurality of programmable logic unit for a plurality of possible functions, and a system for programming same. The integrated circuit also includes a plurality of functional logic blocks, a plurality of input/output (I/O) pads, and programmable logic coupled to each of the plurality of functional logic blocks. The main system processing unit is operable to perform a first function. Each of the plurality of functional logic blocks is operable to perform a respective function. The programmable logic is operable to route data to and from various ones of the plurality of functional logic blocks. The programmable logic is programmable to configure operation of two or more of the plurality of functional logic blocks and is also programmable to create data paths between two or of the plurality of functional logic blocks to configure the integrated circuit for one of the plurality of functions. The plurality of I/O pads is coupled to the main system processing unit and the plurality of functional logic blocks. The I/O pads are operable to transfer data signals between the integrated circuit and an external device. The programmable logic may perform a function different from each of the plurality of functional logic blocks. The system for programming the integrated circuit includes a computer system, the integrated circuit, and a cable for coupling the two.
