Acorn Welcomes New Video Chip

Acorn has welcomed the announcement from Advanced RISC Machines Ltd of
its VIDC20 video controller which has been designed to meet the needs
of a wide range of video systems, from power sensisitive portable
computers through to desktop multimedia workstations. 

This versatile controller can display at up to 16 million colours at
VGA, Super VGA or XGA levels of resolution. Its low power architecture
will drive the LCD screen of a portable computer directly whilst
preserving battery life. It can be used to generate up to 32 bits per
pixel at data rates of up to 160MBytes/second. 

As well as providing a programmable display system, the chip also has
sophisticated audio support.  The device is fully compatible with the
previous VIDC capabilities, providing up to eight channels of stereo
sound. For higher quality multi-media applications requiring both
sound and vision the design provides a straightforward interface to
dedicated sound controllers. 

Acorn Computers' Technical Director, Malcolm Bird confirmed that Acorn
was fully involved in the specification for ARM's new graphics
controller with a view to it being used in future products. "The
VIDC20 is one in a new series of high performance chips from ARM Ltd
that keeps the ARM component set at the forefront of cost effective
technology.  We are leading the test validation programme for the
device and anticipate including it in future generations of
computers." he said.

Advanced RISC Machines (ARM) Ltd was formed in 1990 as a joint company
by Acorn Computers, Apple Computer and VLSI Technology to design and
implement high performance, low cost RISC processors for use in
computers, embedded control systems, digital processing and portable
applications.  ARM has licensed its technology to two semiconductor
product partners - GEC Plessey Semiconductors and VLSI Technology. 
Both manufacture and sell ARM products worldwide.
