TITMS320DM648
Overview
The TMS320DM648 is a high-performance digital media processor based on the C64x+ DSP core, designed for intensive multi-channel video applications. Part of the DaVinci family, it features five configurable video ports and a 3-port Gigabit Ethernet switch to facilitate high-throughput streaming and video analytics. With a clock rate up to 800MHz and specialized VelociTI.2 VLIW extensions, it excels at complex fixed-point signal processing tasks.
Why Choose This Part
The processor provides a robust glueless interface to asynchronous and synchronous memories via its dual EMIFs, reducing external logic complexity. It features a high-performance 64-channel EDMA controller and a dedicated 3-port Gigabit Ethernet switch for efficient data movement without taxing the DSP core. The 529-pin BGA package supports extensive I/O including PCI, SPI, and McASP, making it highly versatile for complex system integration.
Applications
Key Specifications
Getting Started
Development typically requires Texas Instruments Code Composer Studio (CCS) and the Digital Video Software Development Kit (DVSDK). Hardware evaluation can be performed using the DM648 Evaluation Module (EVM) from Spectrum Digital, which provides access to the video ports and Ethernet interfaces. Engineers should utilize the C64x+ DSP Library for optimized signal processing routines.
