Intel demos real-time code compression for die shrinkage, power saving

Intel researchers have developed a way to make the increasingly tiny processors needed to power the impending "Internet of Things" even tinier: compress the code running on them. "We compress the code, make it smaller, and save area and power of integrated on-die memory," Intel Labs senior reseacher Sergey Kochuguev from ZAO …

Is this storage kit the best? It DEPENDS. Why is your face turning red?

Storage marketing is one of maddest and craziest parts of the technology industry: there are so many claims that don’t necessarily stand up to scrutiny and pretty much all of them require the caveat: "It depends…" It is very important to understand that it really does depend on a number of factors. For example, when your flash …
