초록

The PCI 2.2 spec introduces Delayed Transaction mechanism to improve system performance for target device with slow local bus. But this mechanism has some restriction since target device doesn't know prefetch data size. So, we propose a new mechanism, which target device prefetch exact data on local bus, to improve data rate on PCI or local interface. The simulation results showed that the proposed mechanism more improves system performance than the Delayed Transaction mechanism.
