Abstract
In an embedded device with a plurality of processor cores, each core has a static random access memory (SRAM), a memory built-in self-test (MBIST) controller associated with the SRAM, an MBIST access port coupled with the MBIST controller, an MBIST finite state machine (FSM) coupled with the MBIST access port via a first multiplexer, and a JTAG interface coupled with the MBIST access ports of each processor core via the multiplexer of each processor core.
