TMS320DM642AGDK5

Digital Signal Processor Dsp Overview

The TMS320DM642AGDK5 is a video and imaging fixed-point digital signal processor based on the C64x DSP core. It operates at clock rates of 500, 600, or 720 MHz, delivering up to 5760 MIPS. The architecture features eight independent functional units (two multipliers and six ALUs) supporting VelociTI.2 extensions for quad 8-bit and dual 16-bit arithmetic. On-chip memory includes 16 KB L1P cache, 16 KB L1D cache, and 256 KB configurable L2 RAM/cache. Key peripherals include three configurable video ports, a 10/100 Mb/s Ethernet MAC, McASP0, PCI, and an EMIF. The device utilizes a 548-pin BGA package with 0.8-mm ball pitch.

Digital Signal Processor Dsp Procurement Notes

Verify the specific speed grade suffix (-500, -600, or -720) required for the target application frequency. Confirm that the 548-pin BGA package with 0.8-mm ball pitch matches the PCB footprint design. Ensure the voltage requirements align with the selected speed grade, as internal core voltages vary between 1.2 V and 1.4 V depending on the model variant.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed grade based on computational throughput needs; higher frequencies require stricter thermal management. Verify peripheral pin multiplexing constraints, as certain interfaces like PCI, EMAC, and HPI share physical pins. Ensure the development environment supports the C64x instruction set and VelociTI.2 optimizations for efficient code execution.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320DM64x family of digital media processors from Texas Instruments. It is code-compatible with the broader C6000 DSP platform, specifically the C64x generation. The device integrates specialized hardware for video and imaging tasks, distinguishing it from general-purpose C64x variants by including dedicated video ports and multimedia peripherals.

Digital Signal Processor Dsp Replacement Considerations

Direct replacements within the DM64x family include TMS320DM641 and TMS320DM643. These alternatives offer similar C64x cores but may differ in peripheral availability, clock speeds, or package options. Verify software compatibility and pin assignments before substitution.
