However, these traditional debug tools cannot be used when the microprocessor is an embedded core. To overcome this problem we propose the use of an embedded debug and test infrastructure and the IEEE 1149.1 compliance-enable mode to implement the basic functionality provided by an In-circuit emulator and a logic analyser.engEmbedded microprocessorEmbedded debug and test infrastructureIEEE 1149.1 complianceenable modeBoundary Scan Testjournal article2016-12-30
