Multiprocessor-trace concept for system-on-semiconductor chip applications

摘要

A method of retracing data states and instructions in an arrangement, in which a semiconductor chip (SoC) has several processes (1..n), as a result of which, the data (data1..datam) and the instructions (ProC1 to ProCn) of the several processes are each provided with an identification characterising their respective source and in the sequence, as they occur, are written into a FIFO store. The store can then be read via an interface (TI). The data associated with the same time-period, and the instructions of a respective processor are stored in a respective trace telegram.
