Texas Instruments Inc. (TI) has unleashed what it claims as the industry's highest performing multicore digital signal processors (DSPs) based on its TMS320C66x DSP generation. The C66x DSPs are designed for software defined radios (SDRs), radar and surveillance and imaging cameras. TI also said that the devices deliver essential requirements of increasing processing power, accuracy and finer resolution in mission critical applications.

TI's C66x multicore DSPs feature 10GHz DSP with fixed- and floating-point performance on a single device for increased precision, said the company. Additionally, they increase system capabilities by consolidating the functionality of multiple DSPs onto a single device, saving board space and cost and alleviating the challenge of size, weight and power (SwaP), as well as reducing overall clock rates and power consumptions. TI added that the multicore DSPs address interface bandwidth requirements such as SRIO, PCIe and Hyperlink. For applications required to work under extreme physical conditions such as scorching temperatures and sustaining system long shelf life, TI's C66x DSPs offer lead solder ball packages at industrial temperatures.

C66x DSP

TI's C66x DSPs can be used in SDRs, radars and surveillance and imaging systems.

The C66x DSP generation includes the TMS320C6670 radio SoC, a 1.2GHz four core device, boasting improved accelerators for SDRs, public safety and emerging broadband radio systems. The C6670 includes a 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, noted TI. In addition, the programmable CPU cores and configurable accelerators enable SDRs with a simplified programming model. The addition of improved accelerators further helps to develop multistandard communications-centric solutions for the mission critical industry. TI's KeyStone multicore architecture allows developers to use the same platform, across TI's C66x multicore DSPs, for supporting multiple and complex waveforms in SDRs.

TI's multicore DSPs provide a path for parallel processing in order to meet the fast Fourier transform (FFT) processing time requirements in which radar developers can choose to use some or all of the cores. Once FFT performance is met within a radar system, developers can use the other C66x DSP cores to perform pre and/or post processing of the signals or other tasks in the system. In addition, TI's software tools provide full multicore entitlement to determine the best core configuration, allowing developers more flexibility to meet multiple requirements of radar systems, the company said.

With the advent of cloud computing, there is a move for more centralized networks in surveillance applications, as well as a growing demand for advanced video analytics algorithms to assist in managing the increasing number of camera inputs. TI indicated that its C66x multicore DSPs offer many algorithms as well as the ability to easily develop their own algorithms with the company's Vision Library. In addition, TI offers developers advanced codecs, including JPEG 2000, for the best possible image quality, low latency and no inter-frame dependencies that are necessary for many government regulated applications.

In addition to SDRs, radars and surveillance and imaging systems, TI's C66x multicore DSPs have ideal uses in application areas including flight control, routing, servers, video processing networks and security, the company stated.

Development and evaluation of the C66x multicore devices is made easy with comprehensive low cost EVMs available from TI. Designers can begin development on the C6678 multicore DSP with the TMDSEVM6678L for $399. The EVM includes a free MCSDK, Code Composer Studio integrated development environment (IDE) and suite of application/demo codes to allow programmers to quickly come up to speed on the new platform.
