B4860 Overview
-------------
The B4860 QorIQ Qonverge device is a Freescale high-end, multicore SoC based on
StarCore and Power Architecture® cores. It targets the broadband wireless
infrastructure and builds upon the proven success of the existing multicore
DSPs and Power CPUs. It is designed to bolster the rapidly changing and
expanding wireless markets, such as 3GLTE (FDD and TDD), LTE-Advanced, and UMTS.

The B4860 is a highly-integrated StarCore and Power Architecture processor that
contains:
. Six fully-programmable StarCore SC3900 FVP subsystems, divided into three
clusters-each core runs up to 1.2 GHz, with an architecture highly optimized for
wireless base station applications
. Four dual-thread e6500 Power Architecture processors organized in one cluster-each
core runs up to 1.8 GHz
. Two DDR3/3L controllers for high-speed, industry-standard memory interface each
runs at up to 1866.67 MHz
. MAPLE-B3 hardware acceleration-for forward error correction schemes including
Turbo or Viterbi decoding, Turbo encoding and rate matching, MIMO MMSE
equalization scheme, matrix operations, CRC insertion and check, DFT/iDFT and
FFT/iFFT calculations, PUSCH/PDSCH acceleration, and UMTS chip rate
acceleration
. CoreNet fabric that fully supports coherency using MESI protocol between the
  e6500 cores, SC3900 FVP cores, memories and external interfaces.
  CoreNet fabric interconnect runs at 667 MHz and supports coherent and
  non-coherent out of order transactions with prioritization and bandwidth
  allocation amongst CoreNet endpoints.
. Data Path Acceleration Architecture, which includes the following:
. Frame Manager (FMan), which supports in-line packet parsing and general
  classification to enable policing and QoS-based packet distribution
. Queue Manager (QMan) and Buffer Manager (BMan), which allow offloading
  of queue management, task management, load distribution, flow ordering, buffer
  management, and allocation tasks from the cores
. Security engine (SEC 5.3)-crypto-acceleration for protocols such as IPsec,
  SSL, and 802.16
. RapidIO manager (RMAN) - Support SRIO types 8, 9, 10, and 11 (inbound and
  outbound). Supports types 5, 6 (outbound only)
. Large internal cache memory with snooping and stashing capabilities for
  bandwidth saving and high utilization of processor elements. The 9856-Kbyte
  internal memory space includes the following:
