摘要:
A data line pair and a strobe line pair are provided between first and second chips to exchange data therebetween. The first chip includes an output circuit and a controller for controlling the output circuit. The second chip includes an input circuit. For example, the output circuit supplies a direct current from a power supply to one of the data lines. Then, the input circuit feeds back the received current to the output circuit through a pair of terminal resistors and the other data line. Subsequently, the output circuit supplies the fed back direct current to one of the strobe lines. In response, the input circuit feeds back the received current again to the output circuit through another pair of terminal resistors and the other strobe line. And then the fed back current is drained to the ground. Thus, compared to driving the data and strobe line pairs separately with the same amount of current supplied, the current dissipation can be halved. In this manner, the present invention is applicable to reduction of current dissipation when data should be transmitted at high speeds through multiple data bus pairs that are driven with a current supplied.

In an output buffer circuit, an input signal is transmitted through a bus by way of a latch circuit and a driver. A stable-state interval detector detects an interval during which the input signal remains in the same logical state. If the stable-state interval detected is relatively short, a drivability controller controls the drivability of the driver at a normal value. To the contrary, if the interval detected is relatively long, the controller increases the drivability of the driver. In general, if the stable-state interval of an input signal is relatively long, then the time taken for the subsequent logical state transition of the signal tends to be longer as compared with a signal having a shorter stable-state interval. However, if the drivability of the driver is increased, then the state transition time is shortened, and substantially equalized with that of a signal having a relatively short stable-state interval. As a result, signal skewing can be minimized.

A display apparatus of the present invention includes a reception unit configured to receive an image captured by an imaging apparatus from the imaging apparatus and a switching unit configured to switch the display mode of the captured image to a single shooting display mode for displaying the image captured by the imaging apparatus in the single shooting mode or a continuous shooting display mode for displaying the image captured by the imaging apparatus in the continuous shooting mode based on an interval at which the captured image is received by the reception unit.
摘要:
An embroidery data generating device is disclosed. The embroidery data generating device generates embroidery data that is used for sewing an embroidery pattern including multiple color-wise pattern sections with a sewing machine and that includes thread color data specifying a color of each of the color-wise pattern sections. The embroidery data generating device includes a first storage device that stores multiple entries of preset color information; an extractor that randomly extracts color data used as the thread color data from each entry of the color information stored in the first storage device; and an allocator that randomly allocates the color data extracted by the extractor to each of the thread color data associated with each of the color-wise pattern sections.
