Video Port

-TSI capture mode: Transport stream interface (TSI) from a front-end device such as demodulator or forward error correction device in 8-bit parallel format at up to 30 Mbytes/sec.

-The port generates up to three events per channel and one interrupt to the DSP.

A high-level block diagram of the video port is shown in Figure 1–1. The port consists of two channels: A and B. A 5120-byte capture/display buffer is split- table between the two channels. The entire port (both channels) is always configured for either video capture or display only. Separate data pipelines control the parsing and formatting of video capture or display data for each of the BT.656, Y/C, raw video, and TSI modes.

For video capture operation, the video port may operate as two 8/10-bit chan- nels of BT.656 or raw video capture; or as a single channel of 8/10-bit BT.656, 8/10-bit raw video, 16/20-bit Y/C video, 16/20-bit raw video, or 8-bit TSI.

For video display operation, the video port may operate as a single channel of 8/10-bit BT.656, 8/10-bit raw video, 16/20 bit Y/C video, or 16/20-bit raw video. It may also operate in a two channel 8/10-bit raw mode in which the two channels are locked to the same timing. Channel B is not used during single channel operation.

This document describes the full feature set offered by a 20-bit video port implementation. Some devices may offer a subset of features such as video capture only or video display only. Also, some devices may limit the video port width to 8 or 10 bits. In this case, modes requiring wider video port widths such as 16-bit raw, 20-bit raw, and Y/C are not supported. See the device-specific datasheet for details and for I/O timing information.

TMS320C64x DSP specifications

The TMS320C64x DSP family from Texas Instruments represents a significant milestone in the realm of digital signal processing. Launched as part of the C6000 series, the C64x DSPs are designed for high-performance applications requiring intensive computational capabilities, such as telecommunications, audio processing, video processing, and industrial control systems.

One of the standout features of the TMS320C64x DSP is its VLIW (Very Long Instruction Word) architecture, which allows for an exceptionally high level of parallelism. This architecture enables multiple instructions to be executed simultaneously, boosting the overall throughput and allowing for complex data processing tasks to be completed more quickly than with conventional DSPs.

The C64x DSPs also boast an impressive clock frequency range, typically up to 1 GHz, delivering substantial computational power for real-time processing goals. Additionally, these processors feature extensive on-chip memory, including L1 and L2 cache, which significantly enhances data access speeds and helps reduce bottlenecks during high-demand processing tasks.

Another key characteristic of the TMS320C64x family is its support for advanced instruction sets optimized for specific applications. These include SIMD (Single Instruction, Multiple Data) capabilities, allowing for efficient handling of large datasets often involved in multimedia processing or complex signal manipulation.

For connectivity, these DSPs often integrate advanced interfaces such as EMIF (External Memory Interface) and McBSP (Multichannel Buffered Serial Port), facilitating seamless interaction with a variety of peripheral devices. This ensures that the DSP can suit different application needs and integrate well into various system architectures.

Texas Instruments emphasizes low power consumption with the C64x DSPs, making them ideal for portable or energy-sensitive applications. Advanced power management techniques and technologies, such as dynamic voltage and frequency scaling, are incorporated to further enhance energy efficiency without compromising performance.

In summary, the Texas Instruments TMS320C64x DSP family stands out due to its high-performance capabilities driven by a VLIW architecture, high clock speeds, extensive memory options, a rich instruction set, and advanced connectivity features, all while maintaining power efficiency. These characteristics make it an exceptional choice for developers looking to integrate robust digital signal processing into their applications, whether in telecommunications, audio and video processing, or embedded control systems.
