Texas Instruments Inc. unveils the TMS320C6671 device, a DSP in the TMS320C66x DSP generation that offers enhancements to its TMS320C6670 radio SoC. Based on TI's KeyStone multicore architecture, the C6671 DSP is a fast and high performing fixed-and floating-point single core device and offers a viable option to for developers who want to ease into the world of multicore. At the same time, TI's enhanced C6670 radio SoC delivers double the power/performance improvement over existing SoC solutions for communications-centric applications.

TI's C6671 DSP, a 1.25GHz single core member of the C66x DSP generation, utilizes a design approach that familiarises developers with multicore devices without the need for the expertise of working with such a device. Customers designing with the C6671 DSP will benefit from TI's multicore features including increased number of peripherals and memory per core, and fixed-and floating-point performance on a single device.

Using TI's C6671 DSP, developers can test out whether or not multicore devices suit their needs. They can also explore options for migrating their designs to other processors in TI's C66x DSP portfolio if more performance is needed down the road. By offering pin and software compatible platforms across TI's TMS320C6672, TMS320C6674 and TMS320C6678 multicore DSPs, customers can more easily design integrated, power and cost-efficient products for markets such as mission critical, public safety and defense, medical and high-end imaging, test and automation, high-performance computing and core networking.

TI's enhanced C6670 radio SoC is a 1.2GHz four core device boasting improved accelerators for communications-centric applications including software defined radios (SDRs), public safety and emerging broadband radio systems. The added enhancements to the C6670 radio SoC include a new multistandard Bit Rate Coprocessor (BCP) as well as other coprocessors that accelerate physical layer processing for LTE, WCDMA, TD-SCDMA and WiMAX, substantially increasing system capacity and performance with low latency. In addition, the well balanced programmable CPU cores and configurable accelerators enable software defined radios with a simplified programming model. The addition of improved accelerators enables developers to develop multistandard communications-centric solutions for the industry.

TI also announced significant updates to its multicore software and tools, including a free multicore software development kit (MCSDK), Linux software, optimized libraries and support for the OpenMP programming model. TI's software offerings simplify developers' migration to multicore solutions and allow manufacturers to develop a wider portfolio of solutions at a lower cost, lower power, and in less time than with competing solutions.

TI offers evaluation modules (EVMs) to help developers quickly get started with designs using the C6670, C6671, C6672, C6674, or C6678 DSPs. The TMDXEVM6670L and TMDXEVM6678L sell for $399 each and include a free MCSDK, Code Composer Studio (CCS) integrated development environment (IDE) and suite of application/demo codes to allow programmers to quickly come up to speed on the new platform. Order entry is open today for the C6671 DSP, C6670 radio SoC and EVMs. Pricing for the C6671 DSP starts at $79 for 1Ku.
