摘要： A USB host controller is provided. The USB host controller is capable of communicating with multiple USB apparatuses having endpoints and sends a request to a first endpoint. The USB host controller includes a first storage and a first control unit. The first control unit stores endpoint information from the first endpoint into the first storage when the first endpoint issues an unready transaction packet in response to the request. The unready transaction packet indicates that the first endpoint is not ready.
摘要翻译：提供USB主机控制器。 USB主机控制器能够与具有端点的多个USB设备通信，并向第一端点发送请求。 USB主机控制器包括第一存储器和第一控制单元。当第一端点响应于该请求发出未获得的事务分组时，第一控制单元将端点信息从第一端点存储到第一存储器中。未完成的事务数据包指示第一个端点尚未就绪。

摘要： A USB host control method is provided for a USB host controller. The USB host controller includes a USB device and a buffer, the USB device includes one or more endpoints. The USB host control method includes the steps of: storing first output data to be sent to a first endpoint into one or more buffer units used for the first endpoint; sending the first output data to the first endpoint; and when a first predetermined response from the first endpoint is received, configuring fake releasing labels and information tags corresponding to the first endpoint in the one or more buffer units, and not releasing the one or more buffer units.

摘要： A data transmission method for a universal serial bus (USB) host controller is provided. First, input data is received. A cyclic redundancy check (CRC) result of the input data is calculated, and, simultaneously, the input data is transmitted to a system memory of a host. Then, it is determined whether the input data is the last input data of a data packet. When it is determined that the input data is the last input data of the data packet, the CRC result of the last input data of the data packet is calculated. Thus, the CRC result of the data packet is accumulated. The accumulated CRC result is combined with the last input data, and transmitted the combination to the system memory of the host.

摘要： A computer system is provided. In one embodiment, the computer system includes a memory, a peripheral device, a central processing unit (CPU), and a peripheral device controller. The CPU stores information about the data transmission in a descriptor in the memory when data transmission between the CPU and the peripheral device is required. The peripheral device controller reads the descriptor from the memory at an access frequency, records whether the descriptor read from the memory requests for data transmission as a recording result, and adjusts the access frequency according to the recording result.
