Single shared memory space architecture for less power

Virtual Memory and Hardware Memory Pro- tection are so common now that they are even used in hand- held devices that do not include any secondary storage to swap to. As most handhelds depend on batteries for their power supply, it seems worth investigating an architecture without these expensive pieces of hardware. New type safe languages may allow dropping the memory protection hard- ware as well. This paper describes the first investigations done in this direction. Both benefits and drawbacks are described and ways to minimize the drawbacks are inves- tigated.
