September 2000 MediamaticsTM NDV8401 DVD on a Chip Processor Platform The MediamaticsTM NDV8401 DVD on a Chip Processor provides features and cost effective system integration for Universal DVD Players and Internet connected Players/Recorders. Integration of an industry standard RISC processor architecture operating at high performance levels allows system developers to combine the ease of C based application coding with flexible system extensions unavailable in other platforms. This processor can be equally applied to DVD-Video & DVD- Audio playback and Internet Appliance products. Audio quality and flexibility with wide ranging support for all common disc-based audio formats and many Internet based formats. A custom 24-bit DSP has been developed to provide a powerful solution for the latest compute intensive audio algorithms. Support includes DVD-Video, VideoCD and CD formats. The flexible audio structure allows audio data to originate from disc- based media, external digital audio streams or via the Internet. Full 5.1 channel output with simultaneous 2- channel down-mix and IEC958/1937 output is standard for the NDV8401. The NDV8401 provides unsurpassed audio processing Features The NDV8401 is a “system on silicon” solution for consumer DVD Players. Significant feature enhancements are being provided on this version of the NDV8401 device to address both full-featured DVD-Players and DVD-R/W Recorder/Player products. System Solution § Designed for DVD Players with the capability to play DVD-Video, DVD-Audio, VideoCD 2.0, CD-DA, CD-DA in DTS format, and CD-DA with CD-TEXT content § Unified Memory Architecture (UMA) allows sharing of single memory pool for instruction fetch, execution space, system stream demux, video decode, audio decode, video display and audio presentation § Primary clock operating frequency range between 80 – 100MHz based on feature/power requirements § Three on-chip PLLs/Frequency Synthesizers which can generate all required system clocks § Design optimized for 16Mbit & 64Mbit SDRAM operation § Flexible host bus, communication ports & DVD Front-End control to support all DVD system elements Integrated RISC Processor § 32-bit processor with an operating frequency of 67.5 MHz § 2KB instruction cache § 1KB data cache § 1KB local RAM DVD Front End Interface § Supports DVD format, Video CD 2.0 (White Book), & CD-DA (Red Book) § Real time error detection & correction § Supports serial data input with sync search, descrambling, EDC, & serial to parallel formatting blocks § Supports 8-bit parallel data input with selectable bypass of the internal Front End processing blocks § Integrated CSS decryption/descrambling for DVD content MPEG Transport Engine § Accepts input from front end at up to 40Mbps+ § Program Stream demultiplexing § Sub-stream header parsing for DVD MPEG Video Decode § Decodes MPEG1 video & MPEG2 main level, main profile video (720x576) § Maximum input bit-rate of 15 Mbits/sec © 2000 National Semiconductor Corporation www.national.com 1 page
