摘要:
A memory controller which is connected to a memory module having an ECC (Error Check and Correction) function and which controls access to the memory module, the memory controller, has an error detection unit configured to detect an error bit and a position of the error bit by reading, from the memory module, information on codes of the ECCs corresponding to a plurality of read data read from the memory module, a buffer configured to temporarily store the plurality of read data, and a determination unit configured to determine, when the plurality of read data stored in the buffer include a number of data in which a correctable error is detected by the error detection unit and error detection positions of the detected data are the same as each other, that a correctable error is included in a group of the plurality of read data.
摘要:
A system transmits a data packet from a transmitting apparatus to a receiving apparatus. The receiving apparatus includes a receive buffer, and a size specifying information transmitting unit that transmits size specifying information to the transmitting apparatus. The transmitting apparatus includes a transmit buffer, a credit storage unit that stores, as a credit, a value corresponding to a total size of all data packets stored in the receive buffer, a credit adding unit that adds a credit to the stored credit on transmitting a data packet, a credit subtracting unit that specifies a size of a read-out data packet on receiving the size specifying information, subtracts a credit corresponding to the specified size from a stored credit, and a transmission controlling unit that controls data packet transmission based on a credit stored in the credit storage unit.
摘要:
A phase amount added to a clock signal or a plurality of data signals for adjusting a phase relationship therebetween in a reception apparatus is changed, and, a result of the phase adjusting operation is stored when the phase amount added to the clock signal or the plurality of data signals is changed.

摘要:
A selection-signal generating circuit in an LSI being a transmission-side LSI, when a transmission error is detected on an A-side signal line and degeneration control is performed thereon, instructs a selector to select an input from an ECC generator in order to transmit data and ECC data for this data to be transmitted via the B-side signal line, via the A-side signal line. In this manner, the degenerated signal line is used to transmit the ECC data for transmission data to be transmitted via a signal line which is not degenerated.
摘要:
A fixing device according to an embodiment of the present invention heats a metal conductive layer of a heat roller using an induction current generating coil. In order to supplement a heat capacity of the heat roller, a press roller having a large heat capacity is heated by a halogen lamp. During a start of activation of an image forming apparatus, when a printer control circuit is started, the supply of electric power to the halogen lamp is started before warming-up is started.
