CompactPCI DSP Board for 3G Wireless, Broadband and Protocol Transcoding
The seven intelligent DMAs with segmented IXPacket technology provide maximum data throughput and unrivaled transcoding capability for conversion from network IP or ATM protocols. A reprogrammable IXTRIX interrupt multiplexer provides dynamic reallocation of critical systems resources. This board is ideal for the most demanding high data flow, high channel density applications, including VolP, video-conferencing, e-911, wireless networking, and more.
The new high performance DSP board provides support for tightly coupled PMC (PCI Mezzanine Card) expansion modules that allow flexible and expandable I/O modifications with industry standard modules. These PMC expansion sites and Ixthos' strategic Embedded partners create solutions for T1/E1, ATM, DWDM (Dense Wave Division Multiplexing) Fibre, Frame relay OC3/OC48, 10.100 BaseT and Gigabit Ethernet.
The Champ architecture enables for the development of systems based on two scalable, redundant signal processing elements where each SPE "cluster" contains two MPC7400/7410 PowerPC processors running at 400-600 MHz. Each SPE has a dedicated 10/100 BaseT Ethernet interface and all the required resources to send, receive and process voice/data channels with additional I/O data fed through the dedicated PMC sites.
The four signal processing PowerPCs are supported by a core processing element (CPE) which is made up of an additional PowerPC controller (a 250 MHz MPC8240), global memory, semaphores, interrupt multiplexers, a dedicated Ethernet interface, and an H.110 Telephony bus interface. The core processor can process data from any of its I/O sources independent of the SPEs, or seamlessly serve as an I/O manager to DMA data to the four AltiVec processor for concurrent, symmetrical multi-processing.
Independent PCI-PCI data bridges separate the new board's core and signal processors, providing over Gbyte/sec of simultaneous I/O movement, enabling concurrent I/O, Ethernet and CompactPCI bus transfers. Global CPE memory for the CompactPCI CHAMP-AV is 32 or 64 Mbytes of high speed SDRRAM, 64-bits wide. Local memory is 64 to 128 Mbytes of 64 bit wide SDRAM per SPE PowerPC pair. L2 cache is up to 2 Mbytes of SBSRAM (Synchronous Burst SRAM) per processor and FLASH memory is up to 16MB.
CompactPCI Champ-AV software support includes Ixthos' IXATools, used to configure and control the DSPs and all the board level resources and provide a common suite of DSP math libraries. This software suite includes Host/Target support libraries, Smart DMA firmware that presents a command interface to the backplane, and PowerPCs and operating system-specific board support packages. Additional DSP libraries are provided by the comprehensive IXLibs-AV software. Supported operating systems include VxWorks and Linux.
