....other mobile processors on a variety of known industry benchmarks. INTRODUCTION The distinction between Mobile and Desktop computing segments is not new. There are several vectors in which these segments differ, two of which are relevant to our discussion: power dissipation and battery life [1]. Power, Power Density, and Thermal. The overall dissipated power, as well as the power dissipated by the chip per unit area, are important factors. Power generates heat. In order to keep transistors within their allowed operating temperature range, the generated heat has to be dissipated from ....

....and Mac OS X. This hasn t changed much in the last 30 years. For example, back in 1976 Unix version 6 running on a PDP11 used a clock interrupt rate of 60 Hz [16] Since that time the hardware clock rate has increased by about 3 orders of magnitude, from several megahertz to over 3 gigahertz [23]. As a consequence, the size of an operating system tick has increased a lot, and is now on the order of 10 million cycles or instructions. Simple interactive applications such as text editors don t require that many cycles per quantum , making the tick rate obsolete it is too coarse for ....

....of the system clock is not predefined: rather, it is set by the operating system on startup. Thus the system can decide for itself what frequency it wants to use. According to Moore s law, integrated circuit density doubles every 18 months. Hardware clock speeds increase in a similar manner [13]. This has been going on since the 1960 s, and the speed of standard desktop processors now tops 1 GHz. Compared to the typical VAX minicomputers of 20 years ago, a modern microprocessor accomplishes about a thousand times more cycles per second. The operating system clock interrupt rate, on the ....
