Abstract
A system and method for upgrading data transmission performance under programmed input/output (PIO) mode is disclosed. In one embodiment, a PIO accelerating device is established in an IDE controller for handling data transmissions concerned with read/write operations after taking over associated control right from processing unit. A counter is configured in the PIO accelerating device for varying its stored content followed by a predetermined sequence in responsive to the input pulses of a system clock. A timing signal generator is also established in the PIO accelerating device for issuing signals directed to the IDE device and the buffer in the IDE controller for activating associated data transmission operations while the stored content reaches to a predetermined threshold. Optimal performance to data transmission under IO mode 4 of the PIO mode can be achieved by employing the disclosed hardware configuration.
