US Patent 7392032 Modular ASIC with crosspoint switch

Provided is a digital signal processing device, specifically a modular application specific integrated circuit (“ASIC”), having a programmable crosspoint switch for facilitating data transfer and processing within the circuit. A programmable matrix element is operable to perform advanced matrix operations (arithmetic operations) according to user provided commands. The crosspoint switch interconnects the programmable matrix element with various other processing or conditioning modules (i.e. down conversion, filter, pulse processing and demodulation modules) to ensure parallel processing at System Clock rates. The ASIC, which is reconfigurable at a top-level according to user requirements, facilitates design changes and bench testing.
