First Claim
Patent Images
1. A method for accessing data, comprising the step of:
- transferring data registered by a first host controller to a second host controller directly,wherein the transferring further comprises an initialize state, a programming state, and a transfer state, and wherein the CPU is being used to program an operational register of the first host controller for setting the data length, data type, begin/end address, and state of the first host controller while there are data required to be transferred from the first host controller to the second host controller as the transferring is in the programming state.
