Abstract:
1. A method for data accessing, the method comprising: receiving a plurality of transaction layer packets sequentially, each transaction layer packet recording an attribute; accessing a plurality of components corresponding to the attribute of each transaction layer packet, wherein a sequence control step is included to receive data accessing of a write-in transaction layer packet first before receiving data accessing of a read-in transaction layer packet, wherein the attribute of the write-in transaction layer packet indicates snooping the CPU, and the attribute of the read-in transaction layer packet indicates an opposite attribute of the attribute of the write-in transaction layer packet; and temporarily storing data accessed from different components respectively in different buffers of the computer system so that a buffer does not store data of different components; wherein the data is served between a chipset having multiple virtual channels, a peripheral having a single virtual channel, and the components.
