Abstract: A Global Positioning System (GPS) is provided for use by golfers in their golf carts, which supplies useful yardage information to the golfer without the need for frequent manual maintenance by the golf course. Furthermore, the inventive system also comprises a highly effective advertising medium for reaching golfers at the golf course, without being unduly obtrusive. A business method related to providing the GPS system to golf courses benefits those courses by permitting them to obtain the system at no cost, and, in fact, typically at a substantial financial gain, and also permits them to obtain updated and improved golf carts at a substantial discount. Golf courses also benefit because of faster resultant play by golfers on the course, thus permitting them to consider offering more tee times.

Abstract: According to one embodiment of the invention, a prefetcher in a memory controller is described which includes logic to receive memory request hints from a CPU. The memory request hints are used by the prefetcher in the memory controller to prefetch information from one or more memory devices coupled to the memory controller via a memory bus. The prefetcher in the memory controller further includes logic to determine the types of memory request hints provided by the CPU, the types of memory request hints are used to indicate whether the hints provided by the CPU are for instruction memory read request or data memory read request. The prefetcher in the memory controller also includes logic to generate prefetch requests to prefetch information from the one or more memory devices, based on the types of memory request hints provided by the CPU and bandwidth availability of the memory bus.
