MSC8157ETAG1000A

Digital Signal Processor Dsp Overview

The MSC8157ETAG1000A is a six-core digital signal processor utilizing the StarCore SC3850 architecture, manufactured using 45 nm SOI CMOS technology. It integrates six DSP subsystems operating at up to 1 GHz, each equipped with 32 Kbyte L1 instruction and data caches and a unified 512 Kbyte L2 cache. The device features a Chip-level Arbitration and Switching System (CLASS), 3072 Kbyte of M3 memory, and a dedicated Security Engine supporting IPSec, SSL/TLS, and LTE algorithms. Connectivity includes a DDR controller supporting up to 667 MHz clock speeds, a QUICC Engine subsystem for Gigabit Ethernet offloading, and a high-speed serial interface with a 10-lane SerDes PHY.

Digital Signal Processor Dsp Feature Summary

• Six integrated StarCore SC3850 DSP cores with 512 Kbyte L2 cache per core
• Dedicated Security Engine (SEC) with four crypto-channels for IPSec, IKE, SSL/TLS, and 3GPP/LTE
• Second generation Multi-Accelerator Platform Engine for Baseband (MAPLE-B2)
• High-speed serial interface with 10-lane SerDes PHY supporting Serial RapidIO, PCI Express, CPRI, and SGMII

Digital Signal Processor Dsp Applications

• Baseband processing in wireless communication systems
• IPSec and SSL/TLS encryption/decryption hardware acceleration
• LTE protocol stack implementation
• Carrier-grade networking equipment requiring high-throughput packet processing

Digital Signal Processor Dsp Procurement Notes

Verify the specific revision suffix 'A' against the official Freescale Semiconductor datasheet (Document Number: MSC8157E, Rev. 2) to confirm pinout compatibility and electrical characteristics. Ensure that the FC-PBGA-783 package thermal requirements are met within the recommended operating temperature range specified in the datasheet.

Digital Signal Processor Dsp Selection Notes

Select this component when system design requires parallel processing of multiple baseband streams or heavy cryptographic workloads. The inclusion of MAPLE-B2 accelerators makes it suitable for applications needing hardware-assisted Turbo encoding, Viterbi decoding, or FFT processing without burdening the main DSP cores.

Digital Signal Processor Dsp Part Context

This part belongs to the MSC8157 family of six-core digital signal processors from Freescale Semiconductor. It shares architectural similarities with the four-core MSC8154 but provides additional processing resources through two extra SC3850 cores and expanded memory bandwidth capabilities via the CLASS interconnect.
