Gaining RAM For Free, Through Software 68

wakaramon writes with a piece from IEEE Spectrum about an experimental approach to squeezing more usable storage out of a device's existing RAM; the researchers were using a Linux-based PDA as their testbed, and claim that their software "effectively gives an embedded system more than twice the memory it had originally — essentially for free." "Although the price of RAM has plummeted fast, the need for memory has expanded faster still. But if you could use data-compression software to control the way embedded systems store information in RAM, and do it in a way that didn't sap performance appreciably, the payoff would be enormous."
