Floating-point-DSP family adds processors and software Texas Instruments has added the single-core TMS320C6671 to its TMS320C66x family of floating-point DSPs. The device increases clock speed to 1.25 GHz and is pin- and software-compatible with other members of the TMS320C66x family, providing an upgrade path from single-core configurations to two-, four-, and eight-core configurations. The company also has added features to the communications-centric TMS320C6670 SOC (system on chip). These features include a multistandard BCP (bit-rate coprocessor) and accelerators for PHY (physical)-layer processing in LTE (long-term-evolution), WCDMA (wideband-code-division-multiple-access), TDSCDMA (time-division/synchronous-code-division-multiple-access), and WiMax(worldwide-interoperability-for-micro-wave-access) applications. The 1.2-GHz, quad-core C6670 SOC targets use in SDRs (software-defined radios) in applications such as public safety and military radios, which require support for fewer users than cellular-radio base stations. The floating-point DSP also supports emerging applications for processing surveillance video in security and defense applications.
