The choke-point of data flow in almost every EWESM system is the pre-processor. Most ESM systems deal with this condition in several ways 1 restrict sensitivity to decrease the pulse environment 2 sample the environment either through scanning receivers, antennas, or processors. These restrictions impose a compromise on EWESM systems that 1 limit the defense perimeter 2 restrict defenses against Low Probability of Intecept LPI emitters 3 limit RF band coverage 4 restrict operation in high density signal environemnts. Custom and special purpose processors are expensive and often easily compromised. The most effective cost and system processor for EWESM would be a high throughput general purpose microprocessor that could be easily programmed for system needs. Analysis has shown that throughput is basically a function of memory speed matched to Arithmetic Logic Unit ALU speed. Memory speeds have been the principle restrictions on throughput. Special purpose and custom processors have sought to circumvent these restrictions but only at the cost of other undesirable restrictions mention above. With VHSIC technology, there is finally a technology that will permit the high throughput general processor required in EWESM.
