RAM for free

Data compression is standard fare in other parts of the computer business, of course. Speed and power are indeed often critical for embedded computers, as is consistency of response time. So it's no wonder that their designers have shied away from data compression and just added RAM as needed. But it occurred to us that 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. This paper discusses CRAMES, which is a novel data compression, which doubles the memory in embedded system but hardly slows them down.
