"ONE kind of hardware will probably never be virtualised: processors. After all, these are the brains of every digital device. Yet chips, too, are becoming more malleable. Demand is growing for processors that are not just made for a single purpose but can be reconfigured with a special programming tool, a bit like rewritable DVDs. The research arm of Deutsche Bank predicts this segment of the semiconductor market will grow by an annual average of 14% in the next few years.
“Programmable logic devices” (PLDs) help to solve a pressing problem in chipmaking. Developing a custom processor is becoming ever more pricey. Firms may spend up to $40m before the first chip is made. The risk of a design flaw is high, as are the costs of fixing it. PLDs lower both the upfront expense and the cost of getting things wrong. ..."
