A computing device, an operation method of the computing device, and a system on chip are provided. The computing device includes an operator and a resource allocation manager. The operator includes multiple arithmetic units. The resource allocation manager is coupled to the operator and allocates the arithmetic units to a deep learning accelerator and a vector processor for use according to an amount of calculation of the deep learning accelerator and an amount of calculation of the vector processor. The operator receives a first operation request and a second operation request from the deep learning accelerator and the vector processor respectively, uses a first arithmetic unit group of the arithmetic units to perform a calculation of the first operation request, and uses a second arithmetic unit group of the arithmetic units to perform a calculation of the second operation request according to an allocation result.

The disclosure provides a bistable display device and a driving circuit. The bistable display device includes a display panel and the above-described driving circuit, wherein the driving circuit includes a source driver, a first image buffer, a second image buffer, and a timing controller. The source driver is coupled to the display panel to drive the display panel according to a pixel signal. The timing controller is coupled to the first image buffer, the second image buffer, and the source driver. The timing controller alternately selects a first image signal temporarily stored in the first image buffer and a second image signal temporarily stored in the second image buffer as a current image signal and a previous image signal. The timing controller performs a look-up mechanism based on the current image signal and the previous image signal to generate the pixel signal.

A timing controller, a display apparatus, and an operation method thereof are provided. The display apparatus includes a display panel and a timing controller. The timing controller includes a refresh mark controller and a pixel controller. The refresh mark controller includes a refresh mark table, and a plurality of refresh marks in the refresh mark table correspond to a plurality of sub-regions of a display region in the display panel. The refresh mark controller determines whether the sub-regions need to be refreshed according to an image signal and responds to a specific sub-region required to be refreshed to adjust a specific refresh mark according to a mapping ratio. The pixel controller sequentially looks up whether the refresh marks in the refresh mark table are adjusted, obtains the sub-regions corresponding to the adjusted refresh marks according to the mapping ratio, and performs a pixel refresh operation to the sub-regions.

Timing controller, display apparatus, and operation method thereof

A heading calibration method, adapted for a compass sensor is provided. The heading calibration method includes the following steps. R data segments are sequentially generated by rotating the compass sensor by a predetermined angle, wherein the data segments includes a plurality of magnetic data respectively. A partial calibration process is executed to calibrate a reference point coordinate according to the magnetic data in rdata segment and a initial value of the reference point coordinate, wherein r is between 1 and the R. Parts of the magnetic data in the rdata segment is extracted as whole data, and a whole calibration process is executed according to the whole data to update an initial value of the reference point coordinate. The partial calibration process is executed according to the updated initial value of the reference point coordinate and the magnetic data in a (r+1)data segment.

A touch sensor with a sliding structure is disclosed. The touch sensor includes a first touch detecting plate, a second touch detecting plate, and a capacitance-to-digital converter. The first touch detecting plate includes a first tilt portion, and the second touch detecting plate includes a second tilt portion, wherein a bevel edge of the second tilt portion is parallel to a bevel edge of the first tilt portion. The first touch detecting plate and the second touch detecting plate form a parallelogram slide detecting area. The first touch detecting plate transmits a first detected capacitance, and the second touch detecting plate transmits a second detected capacitance. The capacitance-to-digital converter generates a sliding state detected value according to the first detected capacitance and the second detected capacitance.
