Product Overview
Featuring a hybrid signal processing architecture that couples an Altera® Stratix® II FPGA with four ADSP-TS201S TigerSHARC® processors, BittWare’s B2-AMC (B2AM) is an AdvancedMC that supports universal baseband processing for wireless communications infrastructure such as 2G, 2.5G, 3G, WiMAX and SDR. A full-height, single wide AMC, the B2AM attaches to AdvancedTCA (Advanced Telecom Compute Architecture) carriers or other cards equipped with AMC bays and is completely hot-swappable. The B2AM combines an Altera Stratix II FPGA, four TigerSHARCs, a variety of front and back panel I/O interfaces, and a configurable 4x network interface supporting a variety of protocols. It also provides a 10/100/1000 Ethernet interface for command, control, and reprogramming, as well as Flash memory for booting the DSPs and FPGAs.
Altera Stratix II
At the heart of the B2AM is an Altera Stratix II FPGA containing up to 179,400 equivalent LEs, 9.3 Mbits of RAM, 384 embedded 18x18 multipliers, 96 DSP blocks, and 12 PLLs. The FPGA provides pre-, post-, or co-processing to complement the TigerSHARC processing cluster, while also enabling seamless routing of the TigerSHARC I/O via BittWare’s ATLANTiS™ FrameWork, which is implemented in the FPGA.
ADSP-TS201S DSPs
The B2AM features a single cluster of four ADSP-TS201S TigerSHARC DSPs from Analog Devices, providing a total of 14.4 GFLOPS of floating point processing power and 57.5 GOPS of 16-bit fixed point processing power. In addition to 24 Mbits of on-chip RAM, each TigerSHARC also boasts four high-speed LVDS link ports. Each full-duplex link port is comprised of a 4-bit transmit and a 4-bit receive channel, and can support up to 500 MBytes/s in each direction for a total maximum throughput of up to 1 GByte/s. Two link ports from each DSP are used to create an interprocessor communications ring, and the remaining two link ports are routed to the on-board FPGA.
Fat Pipes, Common Options, and I/O Interfaces
The Altera Stratix II FPGA facilitates off-board I/O and provides communications routing and processing. It implements eight TigerSHARC link ports and supports a variety of external I/O, flags, and interrupts. Efficient routing is achieved using BittWare’s ATLANTiS FrameWork, which tightly integrates the DSPs with the I/O peripherals and the FPGA and allows any combination of link ports and off-board I/O interfaces to be routed together, providing nearly infinite options for configuring the I/O.
The Stratix II interfaces to four ports in the AMC fat pipes via PMC Sierra’s QuadPHY SerDes. The four ports provide a network data and control switch fabric interface on the AMC connector, configurable to support PCI Express, Advanced Switching Interconnect (ASI), Serial RapidIO, GigE, or XAUI. A single SerDes port can also be run via a front panel fiber transceiver.
BittWare’s FINe Bridge provides GigE via the common options region, or it can be optionally configured for PCI Express. It also provides 10/100 Ethernet and RS-232 on the AMC front panel.
The Stratix II provides 11 pairs of LVDS I/O (5 Rx, 1 Rx clk, 5 Tx) for proprietary antenna or network interfaces and 24 bits of general purpose digital I/O available on the AMC front panel.
Development Support
A B2-Breakout board (B2B0) is available as a peripheral for the B2AM. The B2B0, only compatible with the B2AM, provides a convenient way to access the board’s signals for test and debug.
Development Tools
BittWare offers complete software support for the B2AM with its BittWorks software tools. BittWorks is a suite of software development tools, designed to make developing and debugging applications for BittWare’s signal processing boards easy and efficient, regardless of whether the hardware is on the local machine or being accessed remotely. The BittWorks software tools include host interface libraries, a wide variety of diagnostic utilities and configuration tools, debug tools, and I/O drivers.
