The middle roadmap vector combines the target apps of Vision/Multichannel and SD Client Video Our TI roadmap leverages DSP, ARM, and Accelerators. ARM: Host processor – works with high-level applications such as Networking and OSs, and enables rich user interfacesDSP: Flexibility for developing any of their own real-time video, audio, speech codecs or non-standard such as H.264 AVS.Accelerators: Can use hardwired accelerators for commoditized type functions to off-load the DSP and enable fast TTM * Get started immediately with our full featured DM365 EVM. This EVM offers Video Input/Output, Audio In/Out, UART, USB 2.0, MMC/ SDIO, and JTAG. It also includes the SW package of Monta Vista Pro 5 with a Linux kernal as well as peripheral drivers, Beta bundled codecs, and uBoot for boot loading. TI customers will also have access to free schematics to give HW development process a fast turn around. And the DM365 EVM will be priced at $595 making it more accessible to our customers. * * DSP 594 MHz, ARM 297 MHz, CoProc – 1 VICP DSP 594 MHz, ARM 297 MHz, CoProc
