Overview The MSC8157/MSC8157E DSP delivers a The MSC8157/MSC8157E embeds 6 MB The MSC8157/MSC8157E is a six-core DSP high level of performance and integration, of internal memory and supports a variety based on Freescale’s new SC3850 StarCore combining six fully programmable new of advanced, high-speed interface types, ® technology and designed to advance the and enhanced SC3850 DSP cores, each including two Serial RapidIO interfaces, capabilities of equipment. running at up to 1 GHz with an architecture two Gigabit interfaces for network ® It delivers industry-leading performance and highly optimized for wireless infrastructure communications, a PCI Express controller, power savings, leveraging 45 nm process applications. Developed by Freescale and one DDR controller for high-speed, industry technology in a highly integrated DSP to integrated on chip, the second-generation standard memory interface and six common provide performance equivalent to 6 GHz MAPLE-B2 baseband accelerator supports public radio interfaces (CPRI). of a single-core device. The MSC8157/ hardware acceleration for Turbo and Viterbi MSC8157E will help equipment manufacturers channel decoding, Turbo encoding and and carriers create solutions and services that rate matching, MIMO MMSE, IRC and ML enable near-term, mainstream adoption of equalization schemes, matrix inversion, CRC next-generation wireless standards such as insertion and check, DFT/iDFT and FFT/iFFT 3G-LTE (FDD and TDD), HSPA+ LTE Advanced calculations and chip rate acceleration. The and WiMAX. The device is designed to lower optional security engine core (SEC) in the system costs by integrating functionality into a MSC8157E accelerates data plane encryption/ single device that previously required multiple decryption and code protection with minimal discrete parts. DSP core intervention.
