TI TMS320C6678ACYPA25

The TMS320C6678 DSP is a highest-performance fixed/floating-point DSP that is based on TI's KeyStone multicore architecture. Incorporating the new and innovative C66x DSP core, this device can run at a core speed of up to 1.4 GHz. For developers of a broad range of applications, such as mission-critical systems, medical imaging, test and automation, and other applications requiring high performance, TI's TMS320C6678 DSP offers 11.2 GHz cumulative DSP and enables a platform that is power-efficient and easy to use. In addition, it is fully backward compatible with all existing C6000 family fixed and floating point DSPs.

TI's KeyStone architecture provides a programmable platform integrating various subsystems (C66x cores, memory subsystem, peripherals, and accelerators) and uses several innovative components and techniques to maximize intra-device and inter-device communication that allows the various DSP resources to operate efficiently and seamlessly. Central to this architecture are key components such as Multicore Navigator that allows for efficient data management between the various device components. The TeraNet is a non-blocking switch fabric enabling fast and contention-free internal data movement. The multicore shared memory controller allows access to shared and external memory directly without drawing from switch fabric capacity.

For fixed-point use, the C66x core has 4x the multiply accumulate (MAC) capability of C64x+ cores. In addition, the C66x core integrates floating point capability and the per-core raw computational performance in an industry-leading 44.8 GMACS/core and 22.4 GFLOPS/core (at 1.4 GHz operating frequency). It can execute 8 single-precision floating point MAC operations per cycle and can perform double- and mixed-precision operations, and is IEEE754 compliant. The C66x core incorporates 90 new instructions (compared to the C64x+ core) targeted for floating point and vector math oriented processing.
