Freescale and Tundra Semiconductor Introduce Development Platform Enabled by RapidIO®

Multi-core MSC8144 DSP and Tsi578™ Serial RapidIO Switch Combine to Enable Bandwidth-Hungry Broadband Systems

Austin, Texas and Ottawa, Ontario – June 20, 2007 — Freescale Semiconductor, a global semiconductor leader, and Tundra Semiconductor Corporation (TSX:TUN), the leader in
System Interconnect today introduced a development platform that combines the industry’s
highest performing programmable digital signal processors (DSPs) and the lowest power
Serial RapidIO (sRIO) Switch available.

The platform leverages Serial RapidIO interconnect technology, using Tundra’s
Tsi578™ switch to cluster four Freescale MSC8144 multi-core DSPs in an AMC
single-width form factor. Tundra and Freescale created the solution to address
interconnect bandwidth requirements of up to 10 Gbps between on-board components in key
applications such as wireless base stations, radio network controllers, media gateways,
video conferencing and radar signal processing. These processing-intensive applications
require high-performance DSPs and the high throughput, low latency characteristics of a
RapidIO solution.

The Tsi578 switch is well suited to interconnect multiple Freescale MSC8144 multi-core
DSPs on a single channel card, enabling an advanced solution that allows base station and
media gateway manufacturers to achieve optimal performance while spanning a wide range of
air interfaces. Interoperability between the two products has already been tested in
Tundra labs and leveraged for the development platform.

“The MSC8144 and Tsi578 deliver a combined solution that is well suited to address the
challenges that manufacturers of high capacity infrastructure equipment face today,” said
Jeff Timbs, Marketing Director for Freescale’s Networking Systems Division. “This
reference design should prove to be a very attractive option for customers seeking
high-performance solutions for communications infrastructure applications such as
AdvancedTCA and MicroTCA.”

Tundra’s Tsi578 enables low latency RapidIO interconnect capabilities at up to 10 Gbps,
thereby supporting the bandwidth-per-link requirements of key applications. Freescale’s
MSC8144 multi-core DSP offers up to 10 Gbps per sRIO port. Customers can take advantage
of the benefits of this platform in standalone mode within MicroTCA and ATCA systems, or
alongside Tundra’s recently announced Tsi578 Serial RapidIO Development Platform.

Tundra’s Tsi578 has successfully passed interoperability testing to DIL-3 certification
by RIOLAB, the world’s only independent Serial RapidIO testing facility. Additionally,
Tundra and Freescale have proven RapidIO connectivity between Tundra’s Tsi578 and
Freescale’s MSC8144 across physical, logical and transport layers.

“The Tundra/Freescale solution offers the aggregate processing power to implement 3G
LTE, WiMAX and TD-SCDMA baseband as well as high density gateway applications,” said
Daniel Hoste, President and Chief Executive Officer, Tundra Semiconductor. “With the
solution, system OEMs can maximize subscribers per line card, while doing
processing-intensive applications such as OFDM Phy processing, and multi-channel video and
voice compression. Leveraging Serial RapidIO interconnect for both chip-to-chip as well as
backplane interconnect, wireless and wireline infrastructure designs can now take full
advantage of the bandwidth processing capability of Freescale’s high performance DSP
clusters enabled by Tundra’s Tsi578 Switch.”

The MSC8144 takes single-chip DSP integration to a new level of sophistication,
combining four StarCore® DSP cores at up to 1GHz each and delivering the industry’s
highest performance, equivalent to a 4GHz single-core DSP. The device integrates a large
embedded memory, enabling higher throughput to memories than external DDR while reducing
chip count and BOM. The part leverages dual RISC QUICCEngine technology at 400MHz to
offload networking protocols, and it offers high speed interfaces such as the x4 Serial
RapidIO and dual SGMII Gigabit Ethernet interfaces.

In February 2006, Tundra launched the Tsi578 Serial RapidIO Switch with multicast
capability, responding to designers’ requirements for low interconnect processing
overhead, lowest power consumption, minimum latency as well as board layout with high
signal integrity. The Tsi578 supports the 1.3 RapidIO specification, and its broad feature
set includes hardware multicast, supervised traffic flow for increased performance and
fabric management, field-proven port flexibility which supports mixed port widths at up to
10 Gbps data speeds, and enhanced SerDes for the lowest power switch solution available.
