TMS320C642x DSPs

TMS320C6424/1 Performance Value DSPs

TMS320C642x DSPs offer more than 2.5X price/performance improvement for telecom and networked DSP applications.
  • Based on the TMS320C64x+™ core, processors have a peak performance of 4800 MMACs at 600 MHz
  • C6424 and C6421 DSPs deliver a 1.6X to 2X boost in raw DSP processing power (e.g. peak 16-bit MMACs), and with a 50 percent price reduction, enable more than a 2.5X price/performance improvement over previous generation DSPs
  • Powerful I/O capabilities enabled by the EDMA 3.0 with 4.8 GB/s throughput and 333 MHz DDR2 memory interface
  • The C6421 DSP at 400 MHz is the lowest cost TMS320C64x™ DSP, and is pin for pin compatible with other C642x DSPs allowing scalability in performance, feature set and price
  • On-chip Ethernet MAC reduces the bill of materials (BOM) for networked DSP applications
  • Large on-chip memory further reduces BOM cost by reducing the need for external memory
