The USB-host-side port is coupled to an input terminal of the first repeater and an output terminal of the second repeater.

When the operation mode is a waiting transaction-start mode, the first repeater operates in a standby state, and the second repeater operates in a power-off state. When the operation mode is a waiting transaction-finish mode, the first repeater and the second repeater transmit transactions between the USB-host-side port and the USB-device-side port.

Abstract: A computing circuit and a data processing method based on a convolutional neural network and a computer readable storage medium are provided. Input data is obtained from a memory. A first computation is performed on first part data of the input data to obtain first output data. The first output data is buffered in a first buffer. When the buffered first output data is greater than a first predetermined data amount, a second computation is performed on the first output data to obtain second output data. The second output data is buffered in a second buffer. Third output data obtained by performing a third computation on the second output data is output to the memory. When performing the second computation on the first output data, the first computation is continuously performed on the input data. Accordingly, the number of accesses of the memory can be reduced.

Abstract: An image controller, an image processing system, and an image correcting method are provided. A first controller obtains a first image from an image capturing apparatus. The first controller converts the first image into a second image according to a converting operation. The converting operation includes deformation correction, and the deformation correction is used to correct deformation of one or more target objects in the first image. A second controller detects the target object in the second image to generate a detected result. The first controller corrects the converting operation according to the detected result. A visual experience may thus be improved in this way.

Abstract: A posture evaluating apparatus, method, and system are provided. An image under test is captured by using an image capturing apparatus. Multiple key points in the image under test are identified. The key points correspond to multiple positions located on the main body and include first and second key point groups.

Each relative position has a corresponding default geometric relation. The default geometric relation and a second geometric relation formed by the association of the second key point group are compared, and a compared result is generated.
