摘要:
Disclosed herein are circuits in which a plurality of clock signals are generated by corresponding clock generators from one or more common clock references. The clock generators accept control values that specify the phases of the individual clocks. The actual phase of each clock signal potentially varies during operation, and the phases of the various clock signal are generally independent of each other. To detect or measure phase relationships, the disclosed circuits evaluate or compare the control values using arithmetic logic.

A method for calibrating a communication channel coupling first and second components includes transmitting a data signal from the first component to the second component on the communication channel, and sensing a characteristic, such as phase, of the data signal on the second component. Information about the sensed characteristic is fed back to the first component using an auxiliary channel. An adjustable parameter, such as phase, for the transmitter is adjusted on the first component in response to the information. Also, a characteristic of a data signal received from the transmitter on the second component is sensed and used to adjust an adjustable parameter for the receiver on the first component.

A method of using additional information at a DMB (Digital Multimedia Broadcasting) receiver is provided. The method includes the steps of: extracting and displaying additional information from a DMB signal; selecting and storing a desired one of the displayed additional information; displaying a list of the stored additional information depending on a user's request command; and outputting additional information selected at the list of the additional information.
摘要:
A system includes a first integrated circuit device and a second integrated circuit device. The first device transmits a data sequence to the second integrated circuit device, and the second device samples the data sequence to produce receiver data. The second device then transmits the receiver data back to the first device. Within the first integrated circuit device, a comparison between the data sequence and the receiver data is performed, and based on the comparison, the first device generates information representative of a calibrated timing offset. The first device uses the information representative of the calibrated timing offset to adjust timing associated with transferring write data from the first integrated circuit to the second integrated circuit.

A memory system includes a master device, such as a graphics controller or processor, and an integrated circuit memory device operable in dynamic memory bank count and page size mode. The integrated circuit memory device includes a first and second row of storage cells coupled to a row of sense amplifiers including a first and second plurality of sense amplifiers. During the first mode of operation, a first plurality of data is transferred from the first plurality of storage cells to the row of sense amplifiers. During the second mode of operation, a second plurality of data is transferred from the first row of storage cells to the first plurality of sense amplifiers and a third plurality of data is transferred from the second row of storage cells to the second plurality of sense amplifiers. The second and third plurality of data is accessible simultaneously from the memory device interface during the second mode of operation. In an embodiment, the second plurality of data is transferred from the first half of the first row and the third plurality of data is transferred from the second half of the second row.
