    摘要: A software self test engine is executed from a cache of a processor. The software self test engine is executed using an execution engine of the processor to perform a physical layer self test. The physical layer self test is performed by transmitting a test vector from the execution engine under control of the self test engine to an input/output (“I/O”) unit of the processor along a datapath coupling the execution engine to the I/O unit. The test vector is transmitted along a loop back path including the I/O unit and the datapath to test a hardware device along the loop back path.
