东芝公司的TC90413XBG是专门用于ATSC LCD HDTV的片上系统（SoC），它集成了从调谐器输出到LCD显示屏接口的所有信号通路。此外，TC90413XBG还支持为了改进视频质量的各种算法。仅采用单一的16位DDR-2接口就能支持统一的存储器架构。器件有多个内部处理器，卸载主MIPS CPU以增加更多的应用功能。本文介绍了TC90413XBG的主要性能，优势以及方框图。
TC90413XBG Single-chip SoC for ATSC LCD TV
概述：
The TC90413XBG is targeted for ATSC LCD TV applications and integrates the entire signal path from the tuner output to the LCD panel interface. Compared to previous Toshiba chips, it integrates more functional blocks on chip reducing system cost. In addition it supports an extensive set of algorithms for improved video quality. It supports a unified memory architecture requiring only a single 16-bit DDR-2 interface. The device has multiple internal processors to offload the main MIPS CPU for value-add applications.
This new SoC TC90413XBG features a level of integration previously unseen in SoCs intended for use in designing mass market HDTVs for the North American market. The TC90413XBG IC incorporates MPEG-2 HD video and Dolby ® Digital audio decoding, a 64-bit 333 MHz MIPS processor, dual HDMI 1.3 ports and a back-end processor capable of driving both WXGA and 1080p display in one chip. Additionally, the TC90413XBG is available as part of TAECs new Customizable Universal DTV Platform (CUDP) for digital television applications, a platform-level solution, which was also announced today, that includes ready-to-manufacture hardware and production software to provide OEMs with a complete HDTV system that is fully customizable to support different international standards and markets.
