Altera Corp. has demonstrated what it touts as the industry's first FPGA Home Agent enabled by the Intel QuickPath Interconnect (QPI) protocol 1.1. Connecting to Intel's Sandy Bridge XEON processors, the solution leverages an Altera Stratix V FPGA configured as the Home Agent, and supports both the Caching Agent and Home Agent in a Pactron Vigor Development Platform. According to the company, the FPGA is geared for designers of low-latency signal-processing, packet processing and embedded applications such as high-frequency trading and big data that need higher computation performance-per-watt than traditional CPU configurations can deliver.

QPI is the only way to coherently connect to an Intel server processor. The Altera StratixV FPGA transceiver has been qualified to support the Intel QPI electrical specification at 8Gb/s. Developers of low-latency, high-bandwidth systems looking to extend the flexible shared memory model that Intel uses for x86 programming can efficiently integrate a Stratix V FPGA into their systems. The Home Agent demo addresses 32GB of memory on the motherboard connected to the socket with support for two channels connecting to four 8GB RDIMMs, detailed Altera.

Pactron designs and develops comprehensive and robust embedded systems that provide storage, wireless, mobile, networked, audio video and internet-connectivity for OEM partners. The company delivers integrated hardware and software platforms that are incorporated into end to end solutions, providing its customers minimised risk, accelerated time-to-market, reduced development costs and enhanced design architecture.

The Altera Stratix V QPI 1.1 IP solution is available. The Pactron Vigor Development Platform is available from Pactron.
