Freescale Semiconductor MSC8157 and MSC8158 Digital Signal Processors

Freescale Semiconductor launched their MSC8157 and MSC8158 digital signal processors (DSP). The new digital signal processors are the next generation of the Freescale MSC8156 DSP. The MSC8157 and MSC8158 DSP devices are based on Freescale’s SC3850 core running at 1.2 Ghz, which recently earned the highest BDTIsimMark2000 fixed-point performance score of any DSP architecture tested to date by independent signal-processing firm Berkley Design Technology, Inc (BDTI). The Freescale MSC8157/58 DSPs will start sampling to selected customers in Q1 2011.

Freescale MSC8157 and MSC8158 DSP Highlights

  • Based on Freescale’s SC3850 core (highest BDTIsimMark2000 fixed-point performance score)
  • 300 Mbps in the downlink and 150 Mbps in the uplink throughputin 3G-LTE 20 MHz bandwidth
  • 4×4 DL and 2×4 UL MiMO
  • Interference cancellation schemes to support hundreds of users
  • Supports multiple WCDMA sectors of 42 Mbps in the downlink and 11 Mbps in the uplink
  • Multi-mode simultaneous operation of 3G-LTE and WCDMA
  • Hardware-accelerated features include FEC, FFT/DFT, MiMO MMSE (Minimum Mean Square Error)
  • MLD (Maximum Likelihood Decoder) flexible equalizers
  • Matrix inversion made possible by floating-point arithmetic and IRC (Interference Rejection Combining) receivers
  • High speed DDR interface
  • Ample internal memory
  • CPRI (Common Public Radio Interface) 6G antenna interfaces
  • Two Serial-RapidIO Gen 2
  • 5G per lane with sophisticated messaging capability
  • Advanced WCDMA Chiprate acceleration (eliminates OEMs’ need to develop their own ASIC or FPGA)
  • Capacity of up to 512 physical channels allows OEMs to deploy their own variant of Chiprate algorithms
  • MSC8157 product supports a broad array of 3G and 4G wireless standards
  • MSC8158 is cost-optimized to enable more efficient and higher throughput deployments for WCDMA networks
  • Enhanced version of MAPLE-B baseband accelerator
