Embedded diagnostics for legacy processor based systems

The need for affordable COTS insertion and advanced diagnostics in legacy weapon systems is widely acknowledged. Furthermore, the upgrade approach of incrementally adding and maturing our systems is becoming increasingly necessary. TRW's RePLACE/sup TM/ technology, which allows for the use of COTS microprocessor technology, legacy software code re-use, and affordable incremental addition of new functionality, is aimed at satisfying these needs. This paper will describe TRW's RePLACE/sup TM/ technology and how it can be used to implement processor-centric diagnostics into legacy systems.
