Abstract:
A display including a supporting layer, a flexible layer and a display structure is provided. The display structure has a top side and a bottom side which are opposite to each other. One of the supporting layer and the flexible layer is disposed at the bottom side of the display structure, and the other one of the supporting layer and the flexible layer is disposed at the top side or the bottom side of the display structure. When the supporting layer and the flexible layer are both disposed at the bottom side of the display structure, the flexible layer is located between the supporting layer and the display structure.
Abstract:
The present invention provides a method of hot switching data transfer rate on the bus to hot switch the data transfer rate of the bus between the control chips without the process of RESET. When the bus between the control chips demands a large amount of data transfer, the bus is hot switched to a higher data transfer rate to fulfill the data transfer requirement. Contrarily, when the bus between the control chips demands less amount of data transfer, the bus is hot switched to a lower data transfer rate to save power consumption.
Abstract:
A data transmission sequencing method is disclosed. A data read operation from a primary bus to a secondary bus can be executed without having to wait for the complete transfer of write data stored in posted write buffer transferring to the primary bus, as long as the secondary bus is not in use. In the mean time of the primary bus issues a read operation to the secondary bus, the secondary bus can issues write operation to the bridging device when the secondary bus is not in use. Similarly, there is no need to wait for the completion of read operation. With this type of data transmission sequencing mechanism, idle sessions in a conventional transmission sequencing method are eliminated leading to a higher data transmission rate.
Abstract:
A two-way cache system for interfacing with a peripheral device and a method of operating a two-way cache system for carrying out data transmission between a peripheral device and a memory unit. The cache system has a two-way first-in first-out buffer region and a two-way cache controller. The two-way first-in first-out buffer region further has a first cache data region and a second cache data region. The first cache data region and the second cache data region are capable of holding a batch of first cache data and a batch of second cache data. The two-way cache controller receives a read request from the peripheral device. According to the read request, the requested data and data that ensues or comes after the requested data are retained by the two-way first-in first-out buffer (FIFO) region. If the peripheral device continues to request more data by maintaining a FRAME signal line in an enabled state, the first cache data region and the second cache data region are alternately used to read in subsequent data. A check may be made to see if requested data stored inside the two-way cache buffer region is coherent or consistent with data stored inside the memory unit.
Abstract:
An expansion adapter is used to communicate both PCI and AGP devices to the north bridge chip of a computer. The expansion adapter includes a first AGP bus control module communicable with the north bridge chip via a first AGP bus, and a second AGP bus control module in communication with the first AGP bus control module, communicable with an AGP device via a second AGP bus. The identifying codes of the first and second AGP bus control modules are set to show no AGP device function in order to allow the AGP device to communicate with the north bridge chip via the expansion adapter. The expansion adapter further includes a PCI bus control module in communication with the PCI device and the first AGP bus control module for controlling data transmission between the first AGP bus control module and the PCI device.

Abstract:
A peripheral device interface control chip having a cache system therein and a method of synchronization data transmission between the cache system and an external device in a computer system. The cache system and data synchronization method can be applied to the peripheral device interface control chip having a data buffer and a peripheral device interface controller. The data buffer is located inside the control chip for holding data stream read from a memory unit so that data required by the peripheral device is provided. When the data stream is still valid, the data stream is retained. The peripheral device interface controller is installed inside the control chip. The peripheral device interface controller detects if the data stream inside the data buffer includes the data required by the peripheral device and whether the data stream is still valid or not. The peripheral device interface controller also controls the placement of the data stream retrieved from the memory into the data buffer and state transition of the data buffer.
Abstract:
Method and apparatus for arbitrating access to a pci bus by a plurality of functions in a multi-function master. The arbitrating method is performed among the multiple functions of a multi-function master. The arbiter includes a rotating inquiry scheduler (RIS) and a heuristic inquiry initiator (HII). The RIS receives the local inquiry signal from the functional circuit and stores it. According to the local inquiry signal, a bus inquiry signal is generated and sent to the HII, and is sent to the PCI bus to request a use of the PCI bus. If the PCI bus responds a delay transaction termination, the HII can repeatedly send the bus inquiry signal to the PCI bus until the PCI bus grants the privilege to use the PCI bus. The HII then informs the RIS, which arranges the functional circuit to transmit data through the PCI bus.
