| B4860QDS |
| ======== |
| |
| The B4860QDS is a Freescale reference board that hosts the B4860 SoC |
| (and variants). |
| |
| 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 |
