         Mercury's Latest Cell BE Processor-Based Offering Enables
      Supercomputer-Like Performance for Rendering, Imaging, and Other
                       Compute-Intensive Applications

    BOSTON, July 31 /PRNewswire-FirstCall/ -- Mercury Computer Systems,
Inc. (NASDAQ: MRCY) announced the Mercury Cell Accelerator Board (CAB), its
latest Cell Broadband Engine(TM) (BE) processor-based product offering, at
SIGGRAPH 2006 (Booth #828, Hall A). The Mercury CAB is the first product
with Cell Technology for commercially available PC workstations.
    "We have been actively working with customers to migrate data-intensive
applications to the Cell BE processor since late last year," said Randy
Dean, Vice President, Business and Technology Development at Mercury. "With
the CAB, customers can achieve supercomputer-like performance right inside
their workstation."
    Featuring the Mercury MultiCore Plus(TM) Advantage, the CAB is designed
to deliver an unprecedented 180 GFLOPS of performance in a PCI Express(R)
ATX form factor suitable for compute-intensive applications such as
rendering, ray tracing, video and image processing, and signal processing.
    The CAB extends the portfolio of Mercury Cell BE processor-based
products, including the BladeCenter(R)-compatible Dual Cell-Based Blade,
the 1U Blade Server, and the highly rugged and deployable PowerBlock(TM)
200 product -- each of which offers a Cell BE processor-based solution.
When deploying the CAB, customers can leverage the Mercury MultiCore Plus
Advantage, including available software development tools and libraries
such as the MultiCore Framework (MCF), optimized Scientific Algorithm
Library (SAL), and the Mercury Trace Analysis Tool and Library (TATL(TM)).
    As with Mercury's other Cell BE processor-based offerings, the CAB
supports Linux via a Yellow Dog(TM) Linux BSP (board support package) from
Terra Soft Solutions.
    The Mercury MultiCore Plus Advantage
    The Mercury MultiCore Plus Advantage employs sophisticated middleware
that abstracts hardware capabilities and manages the distribution of data
across multiple computing elements working in tandem. By leveraging the
MultiCore Plus Advantage from Mercury, customers can benefit from patented
cooling technologies, lightweight system-on-chip (SoC) management software,
multicore implementations of key algorithms, visualization tools designed
for clusters, algorithm tuning, and more.
    Prototypes of the Mercury CAB are now available in limited volumes.
Production availability is planned for the first quarter of calendar 2007.
Pricing for the Mercury Cell Accelerator Board starts at US$7,999 for a
single board, with discounts available on higher volumes. The Cell
Workstation Development System includes a CAB, high-end dual-processor
Opteron workstation running Linux(R) and Windows(R), and the Mercury
MultiCore Plus Advantage software. Contact Mercury for pricing information.
