| 摘要 |
<p>The present invention describes a data processing system containing a data processing device (in form of a microprocessor, CPU, DSP, ASIP, micro-controller, multi-processor system, array of more or less tightly coupled microprocessors, CPUs, DSPs, ASIPs or micro-controllers) and a memory system and where said data processing device performs just-in-time data loading. The key feature of just-in-time data loading is that the access times of the memories where data are stored determine when said the loading of said data may start. In particular, the loading of a datum from some memory is postponed as long as the access time for data read of the memory where said datum is stored still allows the datum to be loaded f. ex. into a load buffer or into a register file of said data processing device just-in-time, e.g. just before the instruction, which uses said datum as an operand, is known or is estimated to begin execution.</p> |
