Linux for Hitachi SuperH Processors

SUNNYVALE, Calif., April 9, 2001 - MontaVista Software Inc., the
company powering the embedded revolution, today announced the
availability of the Hard Hat=81 Linux=AE embedded operating system and
development tools for the Hitachi, Ltd. SH-3 and SH-4
microprocessors. The high performance, low-power SuperH processors
provide an ideal hardware platform for Hard Hat Linux, especially for
target applications in handheld, wireless, consumer, networking and
telematics systems.

With the combination of Hitachi's processors and MontaVista Hard Hat
Linux, and associated development tools, the companies provide
embedded systems designers with the necessary elements to speed
high-performance embedded solutions to market.

"Embedded Linux is a very important OS for our SuperH deployment
program. MontaVista has a solid reputation within the embedded-Linux
community for providing innovative software solutions and superior
technical expertise," said Tadahiko Sugawara, manager, Embedded
System Solution Dept., Semiconductor & Integrated Circuits Group at
Hitachi Ltd. "We will work together to support the growing class of
embedded-Linux designers."

"Our alliance with Hitachi is further proof of the acceptance of Hard
Hat Linux for embedded applications," added Hitoshi Arima, Japan
country manager, MontaVista Software. "Now, Hitachi SuperH-based
embedded designs, in Japan and worldwide, can benefit from the
scalability, robustness and openness of Hard Hat Linux."

MontaVista Hard Hat Linux 2.0 Professional Edition (see accompanying
release) targets the Hitachi SH-3 and SH-4 processors with a
comprehensive tool set of compilers, debuggers, configuration
utilities, and the Hard Hat Linux kernel for Super Hitachi CPUs, and
supports the Hitachi Solution Engine 7709A (SH-3) and 7751 (SH-4)
reference platforms out of the box.   The Hitachi SH series joins
four other microprocessor architectures to give MontaVista unrivaled
CPU breadth and depth for embedded Linux development solutions.

Hard Hat Linux 2.0 Professional Edition is available direct from
MontaVista and MontaVista distribution channels worldwide as a
product subscription, providing the MontaVista Hard Hat Linux kernel,
utilities, development tools and one year of technical support. It is
open source, royalty-free, and built from 100 percent pure Linux

expanded add-on capabilities, including packages for embedded Java,
High-Availability, legacy RTOS porting and emulation, and embedded
GUI development.

MontaVista will also make the Hard Hat Linux 2.0 Journeyman Edition
