RICHARDSON, Texas--(BUSINESS WIRE)--Oct. 14, 1997--Cyrix Corporation (NASDAQ:CYRX) today revealed the
internal architecture of its next processor core, code named Cayenne, at Microprocessor Forum '97.
Cayenne will feature a fully pipelined, dual-issue floating point unit and 15 new MMX floating point instructions to enable the
highest-performance 3D graphics, DVD and 3D audio.
"Future applications will require a no-compromise compute engine with balanced integer, floating point and MMX capability,"
said Robert Maher, vice president of engineering, Cyrix. "The Cayenne core will deliver industry-leading 3D and multimedia
performance for mainstream desktop PCs."
Boost in Floating Point and MMX Performance
A key component of the Cayenne core is the ability to execute four floating point operations per cycle using dual MMX units.
This will deliver over 1 GFLOP peak performance, a first for desktop PCs. In addition, the dual floating point reciprocal and
reciprocal-square-root instructions will execute five times faster on Cayenne than on the Pentium(R) II processor. These
instructions are used extensively in lighting calculations for 3D image processing.
The net result is that Cayenne will deliver in excess of 10 million meshed triangles per second to an external 3D rendering
engine -- more than five times faster than the Pentium II processor. Lastly, Cayenne will deliver single-cycle throughput on
standard x86 floating point instructions.
Cayenne Core Summary
The Cayenne core will feature a dual-issue floating point and MMX unit, 64KByte L1 cache, and an enhanced
sixth-generation integer unit. Processors based on the core will initially be manufactured using a .25-micron, 5-layer metal
process. This includes a C4 process for flip chip assembly. As a result, the core die size is expected to be about
65mm-squared. Processors based on this core are expected to be in production in 2H98 at speed ratings ranging from PR300
to PR400.
