WEITEK announces W464 W564 chipsets with US/DC
Weitek Corp, Jun 08 1995
Weitek Corporation (NASDAQ:WWTK) today announced the W464 and W564, the industry's first Unified
System/Display Controller (US/DC) chipsets.
Weitek's US/DC technology integrates PCI system logic with a high performance 64-bit GUI accelerator,
combining the graphics frame-buffer and main memory into a single 64-bit wide memory subsystem. This
unified memory architecture, due to the elimination of both the separate graphics-frame buffer and a
separate 64-bit graphics controller, allows the most highly integrated and lowest cost PC implementations
available.
The W464 chipset includes a full PCI logic implementation for all popular 486 processors as well as the
Cyrix M1-SC. It also incorporates Weitek's fourth generation high performance 64-bit DRAM-based GUI
accelerator with an integrated 135MHz RAMDAC. The W464 chipset consists of two 208-pin devices, thus
enabling a complete all-in-one PCI motherboard to be designed using fewer VLSI devices than any competing
solution, as well as completely eliminating the expense of a separate graphics frame-buffer. Pricing for
the W464 chipset, which is in PQFP packaging, is $43.50 in quantities of 10,000. Samples of the W464
chipset are available now.
The W564 chipset incorporates PCI support for all leading Pentium-class CPUs, including Intel's P54C,
AMD's K5 and the Cyrix MI. Performance enhancements for the W564 include Weitek's state of the art
video acceleration technology as well as local bus EIDE support and EDO DRAM support. The W564 is slated
for initial availability later this year.
Comments
"We've been anticipating the merger of system memory and graphics in a unified architecture because 16
megabit DRAMs have insufficient bandwidth for graphics, and Weitek is the first to deliver," commented Linley
Gwennap of Microprocessor Report.
Weitek CEO Barry Cox stated, "Our US/DC technology solves the most pressing problem facing PC designers
today: how to deliver the high-performance and rich feature set customers want without the high cost entailed
by solutions with separate 64-bit frame-buffers or exotic specialty memory technologies. By using the most
cost effective commodity DRAMs in an innovative and uniquely efficient way, Weitek's architecture enables
PC vendors to achieve previously unheard-of low price points, while bringing high-performance 64-bit graphics
and multimedia down to baseline PC configurations."
