| |
| 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 |
