In this paper, we introduce a new verification platform with ARM‐ and DSP‐based multiprocessor architecture. Its simple communication interface with a crossbar switch architecture is suitable for a heterogeneous multiprocessor platform. The platform is used to verify the function and performance of a DVB‐T baseband receiver using hardware and software partitioning techniques with a seamless hardware/software co‐verification tool. We present a dual‐processor platform with an ARM926 and a Teak DSP, but it cannot satisfy the standard specification of EN 300 744 of DVB‐T ETSI. Therefore, we propose a new multiprocessor strategy with an ARM926 and three Teak DSPs synchronized at 166 MHz to satisfy the required specification of DVB‐T.
