The Freescale MSC8154AMC reference development system is a high-density, single width, full height DSP platform, based around three MSC8154 DSPs. With a high level of performance and integration, the MSC8154AMC is an well-suited enablement platform for customers and third parties who are developing and debugging solutions for the next generation of wireless standards such as 3G-LTE, WiMAX, HSDPA+ and TDD-LTE.

Each MSC8154 has 1GB of associated 64bit-wide DDR3 memory split into two banks. High throughput RapidIO interface links connect the MSC8154 processors to each other and to the data backplane. The RapidIO interfaces interconnect via the IDT CPS10Q sRIO switch. For the control/data plane, each of the two RGMII gigabyte Ethernet ports links to the backplane ports and a front panel port through an Ethernet switch. A Module Management Controller performs hot swapping and board control.

Freescale also offers a full set of development tools and enablement software for the MSC8154 and MSC8156 DSPs including a highly optimised 3G-LTE software library. Freescale's MSC8156 DSP wireless infrastructure customers are already utilising this 3GPP LTE software kernel library, which provides highly optimised modules for both the uplink and downlink shared channels. The code is delivered with comprehensive test harnesses, documentation and recommendations of how to architect code for interfacing with the MSC8154 or the MSC8156.

Freescale is currently sampling the MSC8154, with general availability planned for October 2009. Housed in a 783-pin FC-PBGA package, it is offered at 1GHz core speeds. Suggested resale pricing is expected to start at Rs.8,059.94 ($165) in 10K volumes. The LTE software is available now, and the MSC8154AMC and MSC8156AMC reference platforms are expected to ship in the first quarter of 2010 for a suggested resale price of Rs.2.93 lakh ($6,000).
