Configurable 9-port PCIe 2.0 Compliant Switch and Multi-port SATA 6GT/s PCIe Compliant Host Bus Adapter Pass PCI-SIG Compliance Tests

BURLINGTON, Ontario— December 6, 2010 —Gennum Corporation’s Snowbush IP
group (TSX: GND) today announced that two of its digital IP cores have achieved PCISIG
® compliance with three new entries added to the PCI-SIG Integrators List. The
Snowbush PCI Express® (PCIe®) 2.0 configurable digital switch IP has been added to the
switches and add-in cards categories, and the Snowbush multi-port PCIe technology to
SATA 6 GT/s host bus adapter IP has been added to the add-in card category. The IP
will facilitate the development of embedded switch and storage products based on the
pervasive PCIe 2.0 standard.

“Our digital IP enables designers to easily add highly complex interconnect functions to
their SOCs, and rapidly migrate to higher bandwidth standards,” said Kevin Walsh,
Marketing Director for Gennum’s Snowbush IP group. “Robust, standards-compliant IP
helps drive down the cost and time-to-market associated with PCIe 2.0 product
development.”

Products on the Integrators List must meet all PCI-SIG testing guidelines set forth at the
PCI-SIG Compliance Workshop, including protocol, electrical, and configuration tests. A
complete and satisfactory PCI Compliance Checklist must also be submitted to the PCISIG.

“Our testing guidelines ensure maximum product interoperability,” said Al Yanes,
President and Chairman, PCI-SIG. “By meeting these compliance and interoperability
requirements with subsystem level IP, the Gennum Snowbush IP group gives the market
an additional solution for deploying PCIe 2.0 compliant products.”

Snowbush PCIe 2.0 Digital Switch IP for Add-in Cards, Systems

Having been certified compliant with the PCIe Base specification revision 2.0, the
Snowbush PCIe switch IP has now passed the PCI-SIG Compliance and Interoperability
Test for add-in cards and systems. The Snowbush IP core is a configurable, nine-port
switch that supports one upstream, and up to eight downstream, ports. Each port can be
configured as x1, x2 or x4. The IP supports maximum payload-only bandwidth of 11.0
gigabits per second (Gbps) in a x4 configuration with low latency. Embedded endpoints
are supported as downstream ports.

The Snowbush PCIe Switch IP was validated and tested using the Dini Group’s
DNMEG_V5T_PCIE daughter card, an FPGA-based emulation platform. Gennum’s
Snowbush IP group uses several of Dini Group’s platforms to validate its complex digital
IPs.

"The combination of this robust IP with Dini Group’s knowledgeable support staff and
leading-edge, FPGA-based hardware emulation platforms gives the market an attractive
solution for rapidly deploying systems and add-in cards based on the PCIe 2.0 standard, ”
said Mike Dini, President for the Dini Group. "Working together with Snowbush IP
ultimately saves cost for our mutual customers, who are developing multi-million gate
SoCs.”

About the PCIe 2.0 Technology to SATA 6GT/s Host Bus Adapter Digital IP

The Snowbush PCIe 2.0 technology-to-SATA 6GT/s host bus adapter IP provides SATA
host functionality through a PCIe bus connection to a system’s main processor. The IP
enables up to 8 SATA ports to be connected to a system’s PCIe bus through a PCIe
endpoint, and can be configured as either x1, x2, x4 or x8. Compliant to the Intel AHCI
specification 1.3 and SATA Specification 3.0, this IP is also ideal for high-performance
SoC applications where the processor bus must be limited to control-only traffic, and in
applications requiring Direct Memory Access (DMA) functions to reduce processor load
and latency.

Availability

The Snowbush PCIe 2.0 9-port switch and PCIe 2.0 technology to SATA 6 GT/s host bus
adapter IP are available immediately for licensing, and are technology-independent. For
