The MSC8156 is based on the industry's highest-performance DSP core built on StarCore technology and designed for the advanced processing requirements and capabilities of today's high-performance applications for the wireless broadband, medical imaging, aerospace, defense and advanced test and measurement markets. It delivers industry-leading performance and power savings, leveraging 45 nm process technology in a highly integrated system-on-chip (SoC) to provide performance equivalent to a 6 GHz single-core device. The MSC8156 helps equipment manufacturers create end products and services that integrate more functionality in a smaller hardware footprint.
The MSC8156 DSP delivers a high level of performance and integration, combining six fully programmable enhanced SC3850 DSP cores, each running at up to 1 GHz. Developed by Freescale and integrated on-chip, the MAPLE-B accelerator supports hardware acceleration for Turbo and Viterbi channel decoding and for DFT/iDFT and FFT/iFFT algorithms. A high-performance 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 MSC8156 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 MSC8156 allows a high degree of scalability through pin compatibility with all MSC825x and MSC815x DSP devices.
