Overview -------- - BSC9131 is integrated device that targets Femto base station market. It combines Power Architecture e500v2 and DSP StarCore SC3850 core technologies with MAPLE-B2F baseband acceleration processing elements. - It's MAPLE disabled personality is called 9231. The BSC9131 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 e500 core subsystem within the Power Architecture consists of the following: . 32-Kbyte L1 instruction cache . 32-Kbyte L1 data cache . 256-Kbyte L2 cache/L2 memory/L2 stash . programmable interrupt controller (PIC) . Debug support . Timers The SC3850 core subsystem consists of the following: . 32 Kbyte 8-way level 1 instruction cache (L1 ICache) . 32 Kbyte 8-way level 1 data cache (L1 DCache) . 512 Kbyte 8-way level 2 unified instruction/data cache (M2 memory) . Memory management unit (MMU) . Enhanced programmable interrupt controller (EPIC) . Debug and profiling unit (DPU) .
