DATA PROCESSING DEVICE, SEMICONDUCTOR DEVICE, DISPLAY DEVICE, CONTROL METHOD AND PROGRAM PRODUCT
A data processing device according to embodiments may comprise: a processor that reconstructs a plurality of update requests for updating at least a part of a display into one or more update requests, or determine that the plurality of the update requests are unnecessary; and an update instruction unit that instructs to execute update processes of the display using the reconstructed one or more update requests.
1 . A data processing device comprising:
a processor that reconstructs a plurality of update requests for updating at least a part of a display into one or more update requests, or determine that the plurality of the update requests are unnecessary; and
an update instruction unit that instructs to execute update processes of the display using the reconstructed one or more update requests.
2 . The device according to claim 1 , wherein
the processor includes
a receiver that receives the plurality of the update requests from an external;
an analyzer that analyzes the plurality of the update requests received by the receiver;
a group generator that groups the plurality of the update requests based on an analysis result of the analyzer; and
a reconstruction unit that reconstructs the plurality of the update request by each group generated by the group generator.
3 . The device according to claim 1 , further comprising a power control instruction unit that switches a power to be fed to the display from a first power to a second power which is greater than the first power during the update processes of the display are executed, wherein
the second power is a power capable of executing an update process of the display.
4 . The device according to claim 2 , wherein the group generator groups update requests which are close in terms of time into a single group.
5 . The device according to claim 2 , wherein
the analyzer specifies an update target region of each update request, and
the reconstruction unit reconstructs update requests included in each group into one or more update requests targeting one or more update target regions including update target regions of the update requests included in the respective groups.
6 . The device according to claim 2 , wherein
the analyzer specifies an update target region of each update request, and
the reconstruction unit generates one or more new update target regions by dividing and/or combining the update target regions included in each group, and reconstructs the update requests included in each group into one or more update requests of the one or more new update target regions.
7 . The device according to claim 2 , wherein
the analyzer specifies update target regions of each update request, and
the group generator groups the plurality of the update requests so that update requests of which update target regions overlap with each other are grouped into the same group.
8 . The device according to claim 2 , further comprising a request history storage that stores a history of past update requests, wherein
the group generator groups the plurality of the update requests based on the history stored in the request history storage.
9 . The device according to claim 2 , wherein
the display executes a periodical refresh of a screen, and
the reconstruction unit abandons an update request which is close to the periodical refresh in terms of time.
10 . The device according to claim 1 , wherein the display is an electronic paper.
11 . The device according to claim 1 , wherein the display has a refresh function.
12 . The device according to claim 1 , wherein at least one of the plurality of the update requests include hint information.
13 . The device according to claim 12 , wherein the hint information includes information indicating that an update request including the hint information is an initial update request or a last update request in a series of update requests.
14 . The device according to claim 13 , wherein the hint information further includes information for identifying the series of the update requests.
15 . The device according to claim 12 , wherein the hint information includes information indicating that the update request with the hint information is an update request to be displayed immediately.
16 . The device according to claim 12 , wherein the hint information includes information indicating that the update request with the hint information requires to be displayed certainly.
17 . The device according to claim 2 , wherein
the analyzer determines whether a size of the update target region of each update request is smaller than a specific size or not, and
the update instruction unit instructs, with respect to an update request of which size of the update target region is smaller than the specific size, to execute an update process thereof without reconstruction by the reconstruction unit.
18 . A display device that executes a single update process in response to two update requests with different issuance times and the same update target region.
19 . A display device that executes two update processes in response to two update requests with different issuance times and the same update target region, and then, when two update requests to the same update target region are issued again, execute a single update process with respect to the reissued two update requests.
20 . A display device in which update times of two regions are different depending on a battery power of an accumulator installed in a data processing device outputting an update request.
