+
+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:
+. 32 Kbyte L1 ICache per e6500/SC3900 core
+. 32 Kbyte L1 DCache per e6500/SC3900 core
+. 2048 Kbyte unified L2 cache for each SC3900 FVP cluster
+. 2048 Kbyte unified L2 cache for the e6500 cluster
+. Two 512 Kbyte shared L3 CoreNet platform caches (CPC)
+. Sixteen 10-GHz SerDes lanes serving:
+. Two Serial RapidIO interfaces.
+ - Each supports up to 4 lanes and a total of up to 8 lanes
+. Up to 8-lanes Common Public Radio Interface (CPRI) controller for glue-less
+ antenna connection
+. Two 10-Gbit Ethernet controllers (10GEC)
+. Six 1G/2.5-Gbit Ethernet controllers for network communications
+. PCI Express controller
+. Debug (Aurora)
+. Two OCeaN DMAs
+. Various system peripherals
+. 182 32-bit timers
