On-Chip Memory Bandwidth Digital Transmission Content Protection
The internal memory architecture allows programs to have four The DTCP specification defines a cryptographic protocol for accesses at the same time to any of the four blocks (assuming protecting audio entertainment content from illegal copying, there are no block conflicts). The total bandwidth is realized intercepting, and tampering as it traverses high performance using the DMD and PMD buses (2 × 64-bit at CCLK speed) and digital buses, such as the IEEE 1394 standard. Only legitimate the IOD0/1 buses (2 × 32-bit at PCLK speed). entertainment content delivered to a source device via another approved copy protection system (such as the DVD content
