ABSTRACT:
A microprocessor includes a processor element, a memory interface element, an IO interface element, a debug support element and an internal bus interconnecting all above elements. For easy debugging, it also includes attached to the internal bus a registered boundary scan standard (JTAG) interface that accesses one or more scan chains inside the microprocessor, and is arranged for controlling DMA-type exchanges via the internal bus with other elements connected to this bus.
