Freescale Semiconductor disclosed that they are leveraging its multi-core processor design expertise and advanced process technology to address customer needs for higher signal processing performance at lower power consumption. Its new 90nm MSC8122 and MSC8126 dsps integrate four starcore DSP cores onto a single die. According to the company, these second-generation multi-core devices are designed to deliver a high-performance, yet cost-effective solution that effectively quadruples performance over single-core DSP offerings.

Embedded system developers are now looking at DSPs as alternatives to higher power, general-purpose microprocessors (MPUs). Compared to multi-core MPUs in the server market that dissipate tens of watts, the low-power MSC812x devices deliver 2GHz and 8 giga multiply accumulates per second (GMACs) of DSP processing power while dissipating 2W. The processing power of these DSPs also enables the convergence of software-driven applications by offering video, voice, fax and modem capabilities on a single platform.

"By offering volume production of our multicore programmable DSPs, Freescale is delivering on our promise to provide embedded systems designers with a high-performance, low-power option to general-purpose single-core DSPs and MPUs," said Lynelle McKay, VP and GM of Freescale's Networking and Communications Systems Division. "Our customers need greater processing power with low power dissipation at a cost-effective price point. The MSC812x devices not only deliver exceptional performance but also offer the benefits of 90nm process technology, which enables low core voltage, lower cost and low power dissipation."

The MSC812x DSPs offer 1.43MB of internal memory, a high bandwidth external memory interface, a rich set of advanced peripherals including an 10/100 Mbps Ethernet controller, and high throughput co-processors, all on an optimized architecture featuring Freescale's best-in-class, multi-core SoC platform design. The MSC8126 features a turbo-coding co-processor (TCOP) and Viterbi co-processor (VCOP) to accelerate wireless baseband processing. All MSC812x devices are binary software compatible with single-core MSC711xx and MSC81xx families and pin-compatible with the first-generation MSC8102 device.

The 300MHz and 400MHz versions of the MSC812x DSPs are offered at an extended temperature range of -40C to 105C. The 500MHz version is offered at standard temperature of 0 to 90C.

The MSC8122 and MSC8126 devices at 500MHz, 400MHz and 300MHz have passed full industrial qualification and are now available for volume production. MSC812x family unit pricing starts at $127.74 in 10,000-unit quantities.
