Overview
|
|
--------
|
|
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
|

NAND boot with 2 Stage boot loader
|
|
----------------------------------
|
|
PBL initialise the internal SRAM and copy SPL(160KB) in SRAM.
|
|
SPL further initialise DDR using SPD and environment variables and copy
|
|
U-Boot(768 KB) from flash to DDR.
|
|
Finally SPL transer control to U-Boot for futher booting.
|
|
|
|
SPL has following features:
|
|
- Executes within 256K
|
|
- No relocation required
|
