Dual-core processor brings real-time DSP performance and reduces power for RISC


Texas Instruments' dual-core OMAP5910 embedded processor combines in a single device the real-time processing capabilities and low power consumption of TI's TMS320C55x DSP core, the flexibility and scalability of a TI-enhanced ARM microprocessor and improved design-in through an optimized interprocessor communication mechanism.OMAP has been used by mobile handset and PDA designers and the OMAP5910 is designed to extend the advantages of the platform to additional consumer, business and industrial applications such as digital media, biometrics, location-based services, enhanced gaming and telematics. The OMAP5910 enables embedded developers to program using familiar development environments by supporting leading operating systems such as Accelerated Technology NucleusPLUS, Microsoft Windows CE .net, Linux Wind River VxWorks and TI's DSP/BIOS real-time scalable kernel. The built-in interprocessor communication mechanism eliminates the need for developers to program the RISC and DSP independently, greatly reducing programming time and complexity. When a RISC processor performs both both real-time, processing-intensive tasks and control functions, performance of each is can be compromised. However, by combining an ARM RISC processor (suited to orchestrating command and control) with a DSP (designed for computation-intensive signal processing tasks), system performance can be optimized, with specific tasks performed by the most appropriate device. The single-chip OMAP5910 also delivers system-on-a-chip functionality with peripherals including: 192Kbytes RAM, USB 1.1 host and client, MMC/SD card interface, multi-channel buffered serial ports, real-time clock, GPIO and UARTs, LCD interface, SPI, uWire and i_s. A battery-operated, hand-held Innovator Development Kit for the OMAP platform is available which supports multiple operating sytsems.Published in Embedded Systems (Europe) October 2002
