Abstract: A multiprocessor SoC(System on Chip) platform and a DVB-T(Digital Video Broadcasting-Terrestrial) baseband receiver using the same are provided to realize flexibility while being suitable for fast operation by using a crossbar switch. A first processor(10) such as a main processor manages entire scheduling and manages communication with an external device. At least one second processor(20a-20c) such as a DSP(Digital Signal Processor) processes a digital signal. At least one slave device(30a-30c) communicates with the main processor and the slave processor. A CI(Communication Interface) unit(40) connects the main processor and the slave device in a crossbar switching mode to enable the main processor and the DSP to communicate with the slave device. The CI unit includes a crossbar switch comprising a plurality of unit crossbar cells for forming a communication path between the main processor and the salve device and between the DSP and the slave device according to the crossbar switching mode, and a CI controller forming the communication path to the slave device when at least one of the main processor and the DSP requests access to the slave device depending on a priority policy.

Abstract: A system-on-chip platform of a cable card satisfying an open cable standard is provided to minimize a time for performing development and verification. An interface block includes a plurality of protocol stacks for supporting the reception limited function about the encrypted transport stream which is provided from a host or a copy guard operation. A password processor(260) exchanges the host and the data through the interface block, and produces a cryptographic key for the subscriber authentication of host and copy guard. At least on of a plurality of protocol stacks is implemented according to the transaction level modeling technique.
