PSC9131RDB is a Freescale reference design board for PSC9131 SoC.The PSC9131 is
integrated SoC that targets Femto base station market. It combines Power
Architecture e500v2 and DSP StarCore SC3850 core technologies with MAPLE-B2F
baseband acceleration processing elements.
The PSC9131 SoC includes the following function and features:
. Power Architecture subsystem including a e500 processor with 256-Kbyte
shared
L2 cache
. StarCore SC3850 DSP subsystem with a 512-Kbyte private L2 cache
. The Multi Accelerator Platform Engine for Femto BaseStation Baseband
Processing (MAPLE-B2F)
. A multi-standard baseband algorithm accelerator for Channel
Decoding/Encoding,
Fourier Transforms, UMTS chip rate processing, LTE UP/DL Channel
processing,
and CRC algorithms
. Consists of accelerators for Convolution, Filtering, Turbo Encoding,
Turbo Decoding, Viterbi decoding, Chiprate processing, and Matrix
Inversion
operations
. DDR3/3L memory interface with 32-bit data width without ECC and 16-bit
with
ECC, up to 400-MHz clock/800 MHz data rate
. Dedicated security engine featuring trusted boot
. DMA controller
. OCNDMA with four bidirectional channels
. Interfaces
. Two triple-speed Gigabit Ethernet controllers featuring network
acceleration
including IEEE 1588. v2 hardware support and virtualization (eTSEC)
. eTSEC 1 supports RGMII/RMII
. eTSEC 2 supports RGMII
. High-speed USB 2.0 host and device controller with ULPI interface
. Enhanced secure digital (SD/MMC) host controller (eSDHC)
. Antenna interface controller (AIC), supporting three industry standard
JESD207/three custom ADI RF interfaces (two dual port and one single port)
and three MAXIM's MaxPHY serial interfaces
. ADI lanes support both full duplex FDD support and half duplex TDD support
. Universal Subscriber Identity Module (USIM) interface that facilitates
communication to SIM cards or Eurochip pre-paid phone cards
. TDM with one TDM port
. Two DUART, four eSPI, and two I2C controllers
. Integrated Flash memory controller (IFC)
. TDM with 256 channels
. GPIO
. Sixteen 32-bit timers
The DSP portion of the SoC consists of DSP core (SC3850) and various
accelerators pertaining to DSP operations.
