Electronic device, method for configuring reprogrammable logic element, computer-readable medium, computer data signal and image forming apparatus
View Patent ↗An electronic device includes a reprogrammable logic element, a configuration data storage, a reading section, a dummy data creating section, a skip determination section, a writing section and a control section. The configuration data storage stores configuration data for the reprogrammable logic element. The reading section successively reads the configuration data from the configuration data storage. The dummy data creating section creates dummy data. The skip determination section determines as to whether or not the configuration data is to be skipped. The writing section writes the configuration data or the dummy data into the reprogrammable logic element. If the skip determination section determines that the configuration data is to be skipped, the control section controls the dummy data, which is created by the dummy data creating section, to be sent to the writing section.
1. An electronic device comprising:
a reprogrammable logic element;
a configuration data storage that stores configuration data for the reprogrammable logic element;
a reading section that successively reads the configuration data from the configuration data storage;
a dummy data creating section that creates dummy data;
a skip determination section that determines as to whether or not the configuration data is to be skipped;
a writing section that writes the configuration data or the dummy data into the reprogrammable logic element; and
a control section, wherein if the skip determination section determines that the configuration data is to be skipped, the control section controls the dummy data, which is created by the dummy data creating section, to be sent to the writing section.
2. The electronic device according to claim 1 , wherein
if the skip determination section determines that the configuration data is not to be skipped, the control section controls the configuration data read by the reading section to be sent to the writing section.
3. The electronic device according to claim 2 , wherein
the control section performs control so that after first configuration data including the dummy data is written into the reprogrammable logic element, second configuration data different from the first configuration data is written into the reprogrammable logic element.
4. The electronic device according to claim 3 , wherein
the configuration data storage stores the second configuration data and does not store the first configuration data.
5. The electronic device according to claim 4 , wherein
the configuration data storage stores data used for checking as to whether or not the first configuration data has been normally written in the reprogrammable logic element.
6. The electronic device according to claim 3 , wherein
the control section partially performs the writing of the second configuration data so as to overwrite at least a part of the dummy data contained in the first configuration data.
7. The electronic device according to claim 1 , further comprising:
a skip information storage that stores skip information indicating a position where the configuration data is skipped, wherein
the skip determination section determines as to whether or not the configuration data is to be skipped, based on the skip information stored in the skip information storage.
8. The electronic device according to claim 1 , wherein
the skip determination section determines as to whether or not the configuration data is to be skipped, based on the configuration data read by the reading section.
9. An image forming apparatus comprising:
the electronic device according to claim 1 .
10. A method for configuring a reprogrammable logic element, the method comprising:
successively reading configuration data for the reprogrammable logic element;
determining as to whether or not the configuration data is to be skipped;
if it is determined that the configuration data is to be skipped, creating dummy data and writing the created dummy data into the reprogrammable logic element; and
if it is determined that the configuration data is not to be skipped, writing the read configuration data into the reprogrammable logic element.
11. A computer-readable medium storing a program that causing an electronic circuit to function as a controller, the controller including:
a configuration data storage that stores configuration data;
a reading section that successively reads the configuration data from the configuration data storage;
a dummy data creating section that creates dummy data;
a skip determination section that determines as to whether or not the configuration data is to be skipped;
a writing section that writes the configuration data or the dummy data into a reprogrammable logic element; and
a control section, wherein if the skip determination section determines that the configuration data is to be skipped, the control section controls the dummy data, which is created by the dummy data creating section, to be sent to the writing section.
