First openly customisable microprocessor

5 May 2004 DSP, Micros & Memory

IBM recently demonstrated Power5, which it claims is the world's most advanced microprocessor. Power5 will be the 'brain' of a new line of powerful IBM computer systems that will be introduced soon. The module pictured holds several Power5 chips on a single ceramic package. Collectively, they contain more than 2,8 billion transistors. The Power5 microprocessor was also demonstrated running multiple operating systems in virtual micropartitions. Currently, IBM uses the chip in its pSeries and iSeries servers. Power5 is a dual-core processor that uses multithreading technology to support as many as two 'virtual processors' per core, which means that as far as the operating system is concerned, it appears to contain four processors. It supports 1024 GBytes of system memory.
