Low-power signal processing chip combines DSP and ARM processor

August 30, 2011 // By Julien Happich
Texas Instruments' OMAP-L132 DSP + ARM processor is what the company announces as the lowest cost and lowest power processor in its OMAP-L1x DSP + ARM processor generation. The chip enables real-time, fixed- and floating-point signal processing, connectivity and communication starting at USD8.55. The OMAP-L132 processor allows entry into cost-sensitive markets and is well suited for power-efficient communications and industrial applications such as software defined radios or programmable automation controllers.

The integrated DSP core supports wireless protocol-specific functions, including signal filtering, modulation/demodulation and modem functions. The ARM processor allows user system management, control and connectivity. The OMAP-L132 is software and pin compatible with several existing TMS320C674x and ARM9-based devices, enabling developers to quickly and easily reuse software and hardware investments to add or remove functionality and expand their product portfolios.

With access to TI’s C6EZRun and C6EZAccel software development tools, developers unfamiliar with DSP can easily develop software on the DSP to achieve unmatched real-time performance while freeing-up the ARM for system control, communications and connectivity. C6EZRun quickly ports ARM code through front-end build scripts to run on the DSP while C6EZAccel provides ARM-side APIs that offer easy access to more than 100 optimized DSP kernels, allowing system developers to add differentiation without needing to write DSP code. The OMAP-L132 processor draws 370mW typical active and 11mW in sleep mode. Integrated peripherals include Ethernet MAC (EMAC), multimedia card/secure digital (MMC/SD) port and high-speed USB 2.0.
