Over 40 TFLOPS of Super-Computing Performance Delivers 5X
     More Processing Power in a Single Rugged, Deployable ISR
                             Subsystem

CHELMSFORD, Mass., June 12, 2012 (GLOBE NEWSWIRE) -- Mercury Computer
Systems Inc. (Nasdaq:MRCY) (www.mc.com), a trusted provider of
commercially developed application-ready ISR and EW subsystems for
defense prime contractors, announced the Ensemble(TM) Series 6000 Dual
AMD GPGPU OpenVPX(TM) GSC6201 module. This new module delivers the
defense industry's highest performing stream processing capability in a
6U form factor. Its flexible, modular design expands the customer's
choice of GPGPU, allowing them to select the best GPGPU for their
application.

The GSC6201 balances the disruptive computational capabilities of AMD's
latest generation Radeon(TM) HD 7970M embedded GPGPU processor with
high-bandwidth I/O interfaces, providing a powerful and scalable
computing architecture that is well aligned with high-end radar,
electronic warfare and image processing applications. With this
product, Mercury leverages multiple open software and hardware
technologies for straightforward interoperability, extensibility and
portability. Among these open technologies is OpenCL(TM), an optimized,
industry-standard software framework that supports code migration among
GPGPUs and other processors for preservation of software IP. Open
industry-standard hardware technologies incorporated within the GSC6201
utilizing AMD include OpenVPX for interoperability, extreme
ruggedization for harsh environmental operation, and industry-standard
MXM technology for rapid tech refresh and performance upgrades to the
latest GPGPU technology.

"Mercury first implemented GPGPUs in 2004 and continues to deliver
defense and commercial GPGPU-based solutions, including a wide range of
currently deployed, high-performance intelligence, surveillance and
reconnaissance (ISR) subsystems," said Scott Thieret, Technical
Director at Mercury Computer Systems. "With AMD's latest Radeon HD
7970M embedded GPGPU and Mercury's StreamDirect(TM) and Imaging
Toolkit, our customers can gain a performance improvement of over 5X
compared with previous AMD solutions, greatly reducing the size,
weight, and power (SWaP) required for real-time on-board exploitation."

"Our strong technology and business relationship with Mercury has
resulted in several AMD successes in the defense industry," said
Richard Jaenicke, director of Embedded Client Solutions at AMD. "We are
thrilled that Mercury has selected the Radeon HD 7970M for their
fourth-generation GPGPU module, and that Mercury has extended the
Radeon HD 7970M's performance capabilities with StreamDirect technology
for direct sensor-to-GPGPU processing, enabling outstanding
performance."

The GSC6201 is available now and can be configured in air-cooled or
conduction-cooled rugged versions.
