in the architecture and design of a custom
hybrid system that supports two industry standard
bus architectures VME and VPX.
The Customer
The Requirement
Solution Provided
A leading Defense Lab selected Mistral to design, build and integrate a system
capable of functioning as a Signal and Data Processing (SDP) Rack.
The customer’s requirement was to design and integrate a solution that met
their overall functional/performance criteria and adhered to longevity, product
life cycle management and integration norms.
Mistral is a professional design services company with extensive experience
in embedded hardware and software development for Mil-Aero applications.
This capability, in conjunction with partnerships with leading embedded
solution providers like Curtiss Wright Controls Defense Solutions and Wind
River Systems, enabled Mistral to provide a complete solution to meet the
customer expectations.

Mechanical design of the SDP Rack with structural and thermal analysis
The rack had to be housed in a sheltered space on a wheeled vehicle
The rack had to be mounted on shock mounts in an air conditioned shelter
and an AC vent had to be provisioned on top of the SDP rack to allow
circulation of conditioned air to the rack for cooling purposes
The rack had to be designed in compliance with JSS 55555 and MIL - STD
461 E and would be subjected to environmental and EMI/EMC tests, at
the customer premises
Design and Fabrication of the hybrid backplane (VPX and VME)
Generation of Wiring Charts, Inter Connection Document (ICD) and
providing cable harnesses as per the ICD
The rack had to be equipped with:
Quad Power PC and Intel based processing system
Quad channel sFPDP module mounted on VPX board capable of
communication using sFPDP protocol
VPX based Gigabit Ethernet Switch
Provision for Redundant Power Supply
Power Supplies for the entire rack. Circuit breakers and protection
circuitry to be provided to prevent damage to the electronics housed
in the rack
The rack had to be mounted with LEDs, to indicate the health of the
power supplies and the fans.
Introduction
The Signal and Data Processing (SDP) Rack is one of the sub-systems in the
radar network which provides resources for radar signal processing, data
capturing and data recording with other radar control functions.
This Case Study highlights Mistral’s expertise in the architecture and
design of a custom hybrid system that supports two industry standard bus
architectures VME and VPX, to meet the requirements of input /output
signals, communication links, processing capability and data transfer
capability.

Integration and testing of COTS and custom designed hardware
Integration of drivers, BSP and DSP libraries
Verification and Validation
Design and validation of the rack for a high-power application, with
thermal management.
Rugged systems adherence to ground based application - All boards
supplied cater to the requirements of JSS 55555 and .
Design and fabrication of 14-slot hybrid backplane comprising of VPX and
VME bus architecture
VPX backplane had to incorporate half mesh fabric connection while
maintaining high level of signal integrity
Conformance to environmental conditions including thermal management,
structural rigidity, EMI/EMC conformance.
Complete integration of the COTS that used two industry standard bus
architectures VPX and VME. The system was realized with two different
operating platforms (Linux and VxWorks)
Power ON sequencing, temperature monitoring and control inside the SDP
Rack
Establishing optical links for sFPDP, Fiber Channel and Gigabit Ethernet for
external and internal network
The integrated SDP rack was qualified i.e. EMI / EMC tests and
environmental tests carried out as an integrated system instead of
qualifying the individual sub-systems. System designed adhered to the
requirements of JSS 55555 and Specifications.
A multi-vendor selection of best-of-breed sub-systems was made available
as an integrated system through a single system integrator; who not only
provided the solution but would also provide support and maintenance for
the coming years
Shortened customer’s end-to-end product development cycle and ensured
on-time deployment schedule
A fully integrated deployable solution, compliant with functional and
environmental standards was made available.
