Patent Searching and Data


Title:
METHOD FOR TRANSFERRING DATA THROUGH BUS BETWEEN TRANSMITTING DEVICE AND RECEIVING DEVICE
Document Type and Number:
Japanese Patent JP3721074
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a method for transferring data through a bus between a transmitting device and a receiving device, capable of increasing bus band width by removing a null cycle.
SOLUTION: This is a method and device for dynamically holding a valid data logic level on a bus by using storage capacity specific to the bus. A bus speed is increased by removing the use of any active bus keeper or null cycle. Instead, a two-phase clock is used, and a bus driver drives data on the bus in the first phase of the clock, and the bus driver is turned off at the beginning of the second phase of the clock. A receiving device latches the data in the second phase of the bus clock. Therefore, it is not necessary to provide any null cycle or bus keeper circuit, and it is possible to prevent any bus contention between continuous drivers or any floating node state.
