The Ensemble® 6000 Series OpenVPX™ with 4th GenerationIntel® Quad-Core™ i7 processor (Haswell mobile class) LDS6525
module from Mercury Systems combines a powerful mobileclass Quad-Core Intel processor, firmware upgradable FPGA
implemented switched 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 thecomputational 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 engine from 128 bit to256 bit, and includes Fused Multiply-Add (FMA), delivering asignificant improvement in floating-point processing.

Mercury Systems is a best-of-breed provider of commerciallydeveloped, open sensor and Big Data processing systems,
software and services for critical commercial, defense andintelligence applications.

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 andthe efficiency of Intel’s FMA.

POET Switched Fabric Interconnect Technology
Mercury’s Protocol Offload Engine Technology (POET™) delivers the highbandwidth, low-latency performance of switched fabrics, providing thebreadth necessary to eliminate data starvation and to fully utilize theupgraded processing power of Intel 4th Generation Core i7 technology.
The LDS6525 POET instantiation supports the high-bandwidth, lowlatency, Gen 2 Serial RapidIO switched fabric and 10Gigabit Ethernet
protocols. Upgrading the data plane protocol is as simple as loadinga new POET image into the local FPGA. The POET interface facilitates
local switching among multiple fabric ports, allowing scalable mesh

Figure 1. LDS6525 functional block diagramand switching based subsystem designs. The open and downloadable
nature of POET allows users of the LDS6525 to implement thesedifferent protocols on the OpenVPX data plane without hardware
changes. Users can also integrate their custom IP with POET toenhance the value of their subsystems.

PCIe Architecture
The LDS6525 provides single 81-lane Gen3 PCIe switches for both onboard switching and off-board expansion. This switch complex
provides an x8 PCIe interface to each of the two XMC sites, as wellas an x4 connection to a PCIe to PCI-X® bridge for the single PMC site.
This allows mezzanines to operate at full bandwidth, optimizing theflow of I/O into the processing subsystem.
Externally, the LDS6525 implements a full Gen3 x16 PCIe connection to the OpenVPX expansion plane on the P2 VPX connector. This
expansion plane interface enables the LDS6525’s compatibility with
Mercury’s GPU or FPGA based co-processing modules. Theseconfiguration options let the module effectively act as an upstream/downstream PCIe switch to allow the “chaining” of PCIe devices.

Mezzanine Card Flexibility
The LDS6525 provides two mezzanine sites: one PMC/XMC and one
XMC-only. Each of the standard mezzanine sites on the LDS6525
module can be configured with off-the-shelf mezzanine cards to bring
additional I/O into the system for processing or control. PMC cards
are supported with a 32-bit or 64-bit PCI/PCI-X interface at up to 133
MHz on the PMC/XMC site, with PMC user-defined I/O mapped to thebackplane. XMCs are supported with x8 PCIe on the J15/J25
connector per the VITA 42.3 standard. There are 16 differential pairs
and 38 single-ended signals of XMC user I/O mapped to the backplane
via the J16/J26 connector.
The LDS6525 supports configuration with either VITA 42 or VITA 61
XMC connectors. Air-cooled variants are populated by default with theVITA 42 XMC connector, while rugged conduction-cooled or Air-FlowBy variants are populated by default with VITA 61 XMC connectors.
The VITA 61 connector offers superior signal integrity characteristics
and is a more rugged design, appropriate for high-end XMC modules
utilizing Gen3 PCIe interfaces in environmentally challenging
applications.

Multiple I/O Options

VPX-REDI

In addition to the flexibility offered via the on-board mezzanine sites,
the LDS6525 offers a variety of additional built-in I/O options:• One 10/100/1000BASE-T Gigabit Ethernet connection can berouted to the front-panel on air-cooled configurations or to thebackplane.

The VPX (VITA 46) standard defines 6U and 3U board formats with amodern high-performance connector set capable of supporting today’shigh-speed fabric interfaces. VPX is most attractive when paired withthe Ruggedized Enhanced Design Implementation standard — REDI(VITA 48). The LDS6525 module is a 6U conduction-cooled/Air FlowBy™ implementation of VPX-REDI, with air-cooled variants in the same
VPX form factor available for less rugged environments.

• One additional 10/100/1000BASE-T Gigabit Ethernet connection
is routed to the backplane.
• Two 1000BASE-BX SERDES Ethernet connections are routed tothe backplane per the OpenVPX control plane specification.
• One TIA-232 serial port is routed to the front-panel on air-cooledconfigurations, or to the backplane on conduction-cooled configurations. When routed to the backplane, the serial interface canbe configured for either TIA-232 or TIA-422 signaling.
• One front-panel USB 3.0 interface is available on air-cooledconfigurations.
• Two backplane USB interfaces are available (one 2.0, one 3.0)
with both air-cooled and conduction-cooled configurations.
• Two SATA interfaces to the backplane are provided to interface
with storage devices.
• Eight GPIO lines act as discrete I/O usable as input, output, or to
generate interrupts on the module.
• Several additional bused signals enhance the functionality of theLDS6525 module.

System ManagementThe LDS6525 module implements the advanced system management
functionality architected in the OpenVPX specification to enableremote monitoring, alarm management, and hardware revision andhealth status. Using the standard I2C bus and Intelligent Platform
Management Controller (IPMC) protocol, the on-board systemmanagement block implements the IPMC.
This allows the LDS6525 module to:• Read sensor values• Read and write sensor thresholds, allowing an application toreact to thermal, voltage or current variations that exceed thosethresholds• Reset the entire module• Power up/down the entire module• Retrieve module Field Replaceable Unit (FRU) information• Be managed remotely by a Chassis Management Controller at
the system level, such as implemented on Mercury’s 6U OpenVPX
switched fabric modules

Targeted primarily for harsh-environment embedded applications,
VPX-REDI offers extended mechanical configurations supporting higher
functional density, such as two-level maintenance (2LM). 2LM allows
maintenance personnel to replace a failed module and restore thesystem to an operational state in a limited time period.

Air Flow-By
Air-cooled chassis require filters to remove contaminants from theircooling air streams. Mercury’s Air Flow-By technology eliminatesfiltration with the most elegant cooling solution available within asealed and rugged package. Air Flow-By technology is resilient, boosts
SWaP, reduces operating temperature, extends MTBF by an order ofmagnitude and enables the most powerful processing solutions.

Additional Features
The LDS6525 module provides all the features typically found on asingle-board computer. In addition to the sophisticated management
subsystem and switched fabric interconnect, the LDS6525 module
provides users with a toolkit enabling many different application use
cases. Features include:• Real-time clock with granularity to 1 ms and time measurementof up to 30 years• General-purpose timers for synchronization• Watchdog timer to support processor interrupt or reset• Multiple boot paths, including netboot, USB boot and boot from
SATA or the on-board 8 GB flash device.

Open Software Environment
Mercury leverages over 30 years of multicomputer software expertise,including recent multicore processor expertise, across its manyplatforms. This strategy is fully applied to the LDS6525 module. Thesame Linux® development and run-time environment is implemented on
the LDS6525 module as on other Intel-based Mercury platforms acrossthe Ensemble 3000, 5000 and 6000 Series. Off-the-shelf open software
such as OFED, OpenMPI and MultiCore Plus™ are fully supported by thePOET enabled data plane.

Open Standards Mean Interoperability and 		Planning for the Future
The OpenVPX/VITA 65 standard is an industry initiative launched bydefense prime contractors and COTS commercial system developers
to take a proactive approach to solving the interoperability issues
associated with the VITA 46 (VPX) family of specifications. This grouphas created an overarching System Specification defining VPX systemarchitecture through pinout definitions to establish a limited set of
application-specific reference solutions. These OpenVPX standard
solutions provide clear design guidance to COTS suppliers and the user
community, assuring interoperability across multi-vendor implementations. The OpenVPX System Specification was ratified by the VSO inFebruary 2010, and it was ANSI approved as the VITA 65 standard inJuly 2010.
