Abstract

In a first aspect, a system is provided that includes a first device that can store data and transfer data. The first device is capable of transferring data at a first rate, although the first device may transfer data at other rates. An intermediate storage location is coupled to the first device, and a second device is coupled to the first device and to the intermediate storage location. The second device includes a processor that is adapted to execute a computer program that requires data to be transferred to the processor at a second rate which is lower than the first rate. Computer program code is provided that can initiate the transfer of data at the first rate from the first device to the intermediate storage location and that can initiate the transfer of data at the second rate from the intermediate storage location to the processor.
