ENSEMBLE® 6000 Series LDS6525 Low Density Server OpenVPX i7

Product Description

The Ensemble® 6000 Series OpenVPX™ with 4th Generation Intel® Quad-Core™ i7 processor (Haswell mobile class) LDS6525 module from Mercury Systems combines a powerful mobile class Intel Quad-Core processor, firmware upgradable FPGA implemented switch fabrics for unsurpassed fabric data rates, and configurable mezzanine I/O in a single 6U OpenVPX slot. The LDS6525, as Mercury’s latest low-density server, provides a next-generation architecture that balances the computational capabilities of the AVX2-enabled Core i7 processor with Gen 2 Serial RapidIO™ or 10 Gigabit Ethernet data paths. The combination provides a powerful and scalable computing architecture that is well aligned with high-end radar, electronic warfare and image processing applications. Intel 4th Generation Core i7 Haswell Mobile-Class Processor.

At the heart of the LDS6525 is the Intel 64-bit 4th Generation Core i7-4700EQ processor, running at up to 2.4 GHz. This processor includes Advanced Vector Extensions-2 (AVX2) instruction set which doubles the width of the processor’s SIMD The 4700EQ includes a large 6 MB cache shared between the cores, allowing many high-performance calculations to remain cache resident. This accelerates processing by eliminating the potential latency required to access DRAM to fetch upcoming data. The processor supports dual high speed DDR3-1600 memory controllers, providing up to 25 GB/s of raw memory bandwidth. 8 GB of DDR3-DRAM with ECC support is populated on the LDS6525.

The four processor cores are supported by the latest on-die GT2 GPU for high definition graphical and intensive parallel data processing. Programming options include the device’s native OpenCL support and the efficiency of Intel’s FMA.
