The MSC8154 device is one of the fourth generation Freescale high-end multicore DSP devices that target the broadband wireless base stations and other communications infrastructure. The MSC8154 is a four-core DSP based on Freescale’s new SC3850 StarCore® technology and designed to advance the capabilities of wireless broadband equipment. It delivers industry-leading performance and power savings, leveraging 45 nm process technology in a highly integrated SoC to provide performance equivalent to a 4Ghz single-core device. The MSC8154 will help equipment manufacturers and carriers create solutions and services that enable near-term, mainstream adoption of next-generation wireless standards such as 3G-LTE, WiMAX, HSPA+ and TDD-LTE. The device is designed to lower system costs by integrating functionality into a single device that previously required multiple discrete parts.
The MSC8154 DSP delivers a high level of performance and integration, combining four fully programmable new and enhanced SC3850 DSP cores, each running at up to 1 GHz with an architecture highly optimized for wireless infrastructure applications. Developed by Freescale and integrated on chip, the MAPLE-B baseband accelerator supports hardware acceleration for Turbo and Viterbi channel decoding and for DFT/iDFT and FFT/iFFT algorithms and includes CRC processing. An internal RISC-based QUICC Engine™ subsystem supports multiple networking protocols to guarantee reliable data transport over packet networks while significantly offloading processing from the DSP cores.
The MSC8154 embeds large internal memory and supports a variety of advanced, high-speed interface types, including two RapidIO® interfaces, two Gigabit Ethernet interfaces for network communications, a PCI Express® controller, two DDR controllers for high-speed, industry standard memory interface and four multi-channel TDM interfaces. The MSC8154 is pin compatible with the MSC8156.
