Montalvo Systems was aSilicon Valley start-up reportedly working on an asymmetrical,x86 capable processor similar to theCell microprocessor. The processor was to use high-performance cores for performance-intensive threads, and delegate minor tasks to the simpler cores to save silicon and power.[1] Matt Perry, formerTransmeta CEO, was CEO and president of Montalvo; Peter Song, founder of failed x86 manufacturerMemoryLogix, was chief architect. Greg Favor (former NexGen/AMD) was responsible for chip microarchitecture and Carlos Puchol (former architect for power management atTransmeta andNvidia) was system and power architect. Another founding member, Kevin Lawton, ofbochs (x86emulation) andplex86 (x86 virtualization) fame, was the processor simulator architect.
The official description of business from Montalvo's security filings[2] was:
A fabless semiconductor company developing ultra low-power system-on-chips for mobile devices.
As of 24 April 2008,Sun Microsystems had acquired the company's assets for an undisclosed sum.[3]
Headquarters were in Santa Clara, California, next door to the remnants ofTransmeta,and nearby to Intel and Sun. It had offices inBoulder, Colorado andBangalore, India. According to news reports, it had close to 300 employees.
In March 2008 news broke that Montalvo was seeking funds to avoid shutdown.[4] According to a news article released on March 31, Montalvo had laid off two-thirds of its engineers. At the same time, rumors surfaced thatSun Microsystems was in talks to buy Montalvo.[5] About three weeks later, on 24 April 2008,The Register confirmed the rumors to be true.[3]
