MSC8157SAG1000A

Digital Signal Processor Dsp Overview

The MSC8157 is a six-core digital signal processor built on 45 nm SOI CMOS technology. It integrates six StarCore SC3850 DSP subsystems operating at 1 GHz, each featuring 32 KB L1 instruction and data caches, and a unified 512 KB L2 cache configurable as M2 memory in 64 KB increments. The device includes a Chip-level Arbitration and Switching System (CLASS), 3072 KB of shared M3 memory, and a DDR controller supporting up to 2 GB of DDR3 memory at 1333 MHz data rate. A second-generation MAPLE-B2 accelerator platform handles baseband processing tasks such as Turbo encoding/decoding and FFT/iFFT. High-speed serial connectivity is provided by a 10-lane SerDes PHY supporting Serial RapidIO, PCI Express, CPRI, and SGMII interfaces.

• DDR controller supporting up to 2 GB DDR3 at 1333 MHz data rate
• 10-lane SerDes PHY with Serial RapidIO, PCI Express, CPRI, and SGMII

Digital Signal Processor Dsp Applications

• Baseband processing for wireless communication systems
• Telecommunications infrastructure equipment
• High-performance digital signal processing applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific revision level against the datasheet Rev. 3 documentation. Confirm package compatibility with the FC-PBGA-783 footprint measuring 29 mm x 29 mm. Ensure power supply designs account for the multiple distinct voltage rails including GVDD, NVDD, QVDD, VDD, and CPRIVDD specified in the ball list.

Digital Signal Processor Dsp Selection Notes

Select this component when high-throughput parallel processing is required for complex algorithms like Viterbi decoding or matrix inversion. Evaluate the MAPLE-B2 hardware accelerators to determine if they reduce the load on the six DSP cores. Verify that the available I/O count meets the requirements for the target Serial RapidIO, PCI Express, and Ethernet interface configurations.
