Transmeta Innovation Timeline
Dave Ditezel, of RISC-fame and formerly from SPARC, started up Transmeta as its CEO in 1995.
The first Patent (5958061) was applied in July 24, 1996 granted in September 28, 1999.
On January 19, 2000 the Crusoe processor was published.
Crusoe became famous as an x86 compatible family of solutions that combines strong performance with remarkably low power consumption.
Characteristics of Crusoe contd.
LongRunDynamic Power Management
Enables low power operation by dynamically adjusting operating frequency and voltage to match the performance requirements of application workloads.
Provides higher performance within smaller, thermally constrained environments
Enables fanlessdesigns for quieter and more reliable systems
