Here's some info on Crusoe that I haven't seen before. They say the 700 MHz version is (or, should I say, WILL BE) about equivalenet to a PIII-500 in benchmark (unspecified) performance. From embedded processor watch: *** Transmeta Unveils Crusoe Chips After nearly five years of unprecedented secrecy, Transmeta (http://www.transmeta.com/) has revealed a new approach to x86 CPU design -- VLIW chips that it claims are part hardware and part software. Transmeta achieves x86 compatibility by emulating the x86 architecture with hardware-assisted software. The technology is similar to the x86 emulators sold by Insignia Solutions and Connectix for the Macintosh, and it also has much in common with the Java just-in-time (JIT) compilers built into popular Web browsers. The hardware features built into Transmeta's Crusoe chips reduce the overhead of emulation, but there's still some penalty, so the 400- and 700-MHz clock speeds of the processors cannot be directly compared to the frequencies of other x86-compatible chips. Even so, Transmeta has created two processors with some attractive characteristics. According to company founder Dave Ditzel, the power dissipation of the Crusoe chips is typically around one watt -- much less than any current mobile x86 processor from Intel, AMD, VIA, or Rise. Although Transmeta did not disclose definitive performance benchmarks, it claimed that the high-end 700-MHz TM5400 Crusoe chip will deliver roughly the performance of a Pentium III-500 on PC applications. Transmeta's lower-end TM3120 Crusoe chip peaks at 400 MHz with similar power-consumption characteristics. It's intended for non-PC information appliances and other embedded applications. Transmeta has created a specially compacted version of Linux that's optimized for "Webpads" and similar devices. If Transmeta's power ratings are close to accurate, the company may capture a significant number of sockets in today's thin-and-light notebooks and tomorrow's Web-enabled embedded appliances.--K.D.
