Multicore DSPs deliver performance and low power in small form factor

March 27, 2012 // By Paul Buckley
Texas Instruments has unveiled three devices based on its KeyStone multicore architecture utilizing the TMS320C66x DSP generation. The TMS320C665x DSPs feature combined fixed- and floating-point capabilities, delivering real-time high performance at low power coupled with smaller form factors.

With the TMS320C6654, TMS320C6655 and TMS320C6657 multicore DSPs, developers can more effectively meet vital requirements of high performance and portable applications in markets such as mission critical, industrial automation, testers, embedded vision, imaging, video surveillance, medical, audio and video infrastructure.

Based on the KeyStone multicore architecture, the C665x processors offer developers access to devices that are high performance while still being power and space efficient. The low power consumption and small form factor of 21 mm x 21 mm enable portability, mobility and low power energy sources such as battery and interface powering to drive breakthrough products.

The strengths of these C665x DSPs meet the need of applications such as video security and traffic management, where there is a need to carry out both video processing and analytics at the end point. In addition, a wide range of high performance real-time applications such as on-board radar, software defined radios, video and image processing and portable ultrasound will now be smaller, lighter and easier to use.

The C665x DSPs also feature large on-chip memory coupled with a high bandwidth and efficient external memory controller, making them an ideal choice for developers of mission critical, test and automation, imaging, medical and audio and video infrastructure applications where low latency is critical.

The DSPs support extended temperature ranges from -55 to 100°C for applications required to work under extreme physical conditions or provide sustained operating life. This feature makes the C665x DSPs ideal for mission critical, outdoor imaging and analytics applications, where high reliability is a key requirement. In addition, the C665x DSPs provide abundant performance and connectivity to tackle the challenging specifications in imaging applications, including high bandwidth serial interfaces such as RapidIO, PCIe and Gigabit Ethernet and the ability to extend processing to a pool of DSPs.

An optimized set of peripherals, including Universal Parallel Port (UPP) and Multichannel Buffered Serial Ports (McBSP), in the C665x processors, reduce system cost and
