ABSTRACT:
A field programmable, digital signal processing integrated circuit is formed in a semiconductor die and includes an array of arithmetic logic (ALU) circuits. A user programmable interconnect architecture is superimposed on the array of ALU circuits. One or more interface circuits comprising digital-to-analog (D/A) converters or analog-to-digital (A/D) converters are provided on the integrated circuit to interface to off-chip analog input signals and provide off-chip analog output signals. Circuitry is provided to program the interconnections between the interface circuits and the ALU circuits and between individual ones of the ALU circuits, as well as to define the specific functions of the individual ALU circuits.
