The first of a planned series of DSP/RISC multicore platforms – called DaVinci –were rolled out by Texas Instruments, Inc. this week, designed to simplify the design of a myriad of digital video systems.
The first devices in this family are the TMS320DM6443 and the TMS320DM6446. The 6443, tuned for video decode applications, provides all of the processing components required to decode digital video, including both analog and digital video output with integrated resizer and on-screen display (OSD) engines.
According to Greg Mar, DSP SoC platform manager, TI, the DM644x devices are built around a TMS320C64x+ DSP core, an ARM926 processor, video accelerators, networking peripherals and external memory/storage interfaces all specifically tuned for video.
Supporting the hardware, he said, is a complete software infrastructure, from low-level OS drivers to application APIs, with the aim of making it possible for developers to implement digital video without having to focus resources on writing and optimizing codecs or programming a DSP.
Initially, based on the Linux Operating System, these APIs are designed to mask the complex hardware and software details of implementing codecs from developers, enabling them to interchange multimedia codecs without having to modify application code. Optimized video and audio codecs are also available for free evaluation and licensing from TI to simplify and speed customer design and decision making.
To support developers in their evaluation of the platform, TI is also making available the Digital Video Evaluation Module (DVEVM) containin the MontaVista 2.6.10 Linux Preview Kit and MontaVista GNU development tools.
In addition, said Mar, the DV-EVM includes a NTSC/PAL camera, LCD screen, pre-wired video encode and decode codec demos and the ability to create new demos with original video streams. The DVEVM also offers connectivity to video input/outputs, networking interfaces, storage interfaces and standard daughter card connections, so developers can use the DVEVM for their application prototypes.
Also available for use with the platform is the company’s Code Composer Studio Integrated Development Environment.
The TMS320DM6443 and TMS320DM6446 are pin-for-pin and software-compatible, as well as being code compatible with previous generations of TMS320DM644x devices and are sampling immediately. The DM6443 is $29.95 and the DM6446 is $34.95, both in quantities of 10KU in 2006. The DVEVM (TMDXEVM6446) is $1995 and available for order entry.
