The TMS320C6454 DSP from Texas Instruments is a 1 GHz DSP based on the improved TMS320C64x+ DSP core and highest-performing DSP architecture. The DSP provides developers with twice the memory and I/O bandwidth of the popular TMS320C641x DSPs, as well as other advanced features needed for next-generation systems.

The C6454 DSP provides a migration path for the many TI customers who are currently using C641x DSPs by offering full code compatibility and boosted performance without requiring additional investment in software engineering. The C6454 DSP achieves 8000 million multiply accumulate cycles per second (MMAC) and four times the enhanced direct memory access (EDMA) throughput of the core used in the earlier devices. The DSP also provides additional features, such as 1 MB L2 memory, gigabit Ethernet, C64x+ core and increased DDR2 external memory and cache, and is similarly priced to C641x devices.

For customers who are using the closely related TMS320C6455 DSP, which is TI’s first mass market product using the C64x+ core and includes a sRIO bus interface to support the interprocessing requirements of bandwidth-intensive applications, the cost-efficient C6454 DSP offers C64x+ peak performance at an affordable price. Designers can immediately begin code development for tomorrow’s C6454 DSP products using the C6455 evaluation module (EVM) and DSP Starter Kit (DSK).

The C6454 DSP offers designers a 20% to 30% reduction in code size to decrease system costs. It also achieves a 20% increase in cycle efficiency due to the core’s specialized instruction set with support for the frequently performed FFT, FIR and DCT operations.
