3The B4860QDS is a Freescale reference board that hosts the B4860 SoC (and variants).
4
5B4860 Overview
6-------------
7The B4860 QorIQ Qonverge device is a Freescale high-end, multicore SoC based on
8StarCore and Power Architecture® cores. It targets the broadband wireless
9infrastructure and builds upon the proven success of the existing multicore
10DSPs and Power CPUs. It is designed to bolster the rapidly changing and
11expanding wireless markets, such as 3GLTE (FDD and TDD), LTE-Advanced, and UMTS.
12
13The B4860 is a highly-integrated StarCore and Power Architecture processor that
14contains:
15. Six fully-programmable StarCore SC3900 FVP subsystems, divided into three
16clusters-each core runs up to 1.2 GHz, with an architecture highly optimized for
17wireless base station applications
18. Four dual-thread e6500 Power Architecture processors organized in one cluster-each
19core runs up to 1.8 GHz
20. Two DDR3/3L controllers for high-speed, industry-standard memory interface each
21runs at up to 1866.67 MHz
22. MAPLE-B3 hardware acceleration-for forward error correction schemes including
23Turbo or Viterbi decoding, Turbo encoding and rate matching, MIMO MMSE
24equalization scheme, matrix operations, CRC insertion and check, DFT/iDFT and
25FFT/iFFT calculations, PUSCH/PDSCH acceleration, and UMTS chip rate
26acceleration
27. CoreNet fabric that fully supports coherency using MESI protocol between the
28  e6500 cores, SC3900 FVP cores, memories and external interfaces.
29  CoreNet fabric interconnect runs at 667 MHz and supports coherent and
30  non-coherent out of order transactions with prioritization and bandwidth
31  allocation amongst CoreNet endpoints.
32. Data Path Acceleration Architecture, which includes the following:
33. Frame Manager (FMan), which supports in-line packet parsing and general
34  classification to enable policing and QoS-based packet distribution
35. Queue Manager (QMan) and Buffer Manager (BMan), which allow offloading
36  of queue management, task management, load distribution, flow ordering, buffer
37  management, and allocation tasks from the cores
38. Security engine (SEC 5.3)-crypto-acceleration for protocols such as IPsec,
39  SSL, and 802.16
40. RapidIO manager (RMAN) - Support SRIO types 8, 9, 10, and 11 (inbound and
41  outbound). Supports types 5, 6 (outbound only)
42. Large internal cache memory with snooping and stashing capabilities for
43  bandwidth saving and high utilization of processor elements. The 9856-Kbyte
44  internal memory space includes the following:
45. 32 Kbyte L1 ICache per e6500/SC3900 core
46. 32 Kbyte L1 DCache per e6500/SC3900 core
47. 2048 Kbyte unified L2 cache for each SC3900 FVP cluster
48. 2048 Kbyte unified L2 cache for the e6500 cluster
49. Two 512 Kbyte shared L3 CoreNet platform caches (CPC)
50. Sixteen 10-GHz SerDes lanes serving:
51. Two Serial RapidIO interfaces.
52	- Each supports up to 4 lanes and a total of up to 8 lanes
53. Up to 8-lanes Common Public Radio Interface (CPRI) controller for glue-less
54  antenna connection
55. Two 10-Gbit Ethernet controllers (10GEC)
56. Six 1G/2.5-Gbit Ethernet controllers for network communications
57. PCI Express controller
58. Debug (Aurora)
59. Two OCeaN DMAs
60. Various system peripherals
61. 182 32-bit timers
