Method and related apparatus for controlling a peripheral device to transfer data to a bus

Abstract

A method and related apparatus used for controlling a peripheral device to transfer data to a bus. The peripheral device has a bus interface circuit and a controller. The method includes storing data outputted from the controller into a first storage block of the bus interface circuit, utilizing the bus interface circuit to simultaneously control the first storage block to output its stored data to the bus and control a second storage block of the bus interface circuit to store data outputted from the controller, and utilizing the bus interface circuit to control the second storage block to output its stored data to the bus.

1 . A method of controlling data outputted from a peripheral device, the peripheral device being installed on a computer system, the peripheral device comprising a bus interface circuit and a controller, the bus interface circuit comprising a plurality of storage blocks and being electrically connected to a bus of the computer system for controlling data transmission between the peripheral device and the bus, the controller being electrically connected to the bus interface circuit, the method comprising: 
 storing data outputted from the controller to a first storage block; and    transferring the stored data from the first storage block to the bus and simultaneously storing data outputted from the controller to other storage blocks;    wherein the data transfer rate between the controller and the bus interface circuit is not less than the data transfer rate between the bus interface circuit and the bus.    
   
   
       2 . A computer system comprising: 
 a bus;    a bus interface electrically connected to the bus, the bus interface having a plurality of storage blocks; and    a controller electrically connected to the bus interface for simultaneously controlling the transfer of stored data from a first storage block to the bus and storing data from the controller to other storage blocks;    wherein the data transfer rate between the controller and the bus interface is not less than the data transfer rate between the bus interface and the bus.    
   
   
       3 . The computer system of  claim 2  wherein the bus interface further comprises: 
 a first switch electrically connected between the bus and the storage blocks for selectively connecting the bus to one of the storage blocks; and    a second switch electrically connected between the controller and the storage blocks for selectively connecting the controller to another one of the storage blocks;    wherein the first switch and the second switch are respectively connected to different storage blocks.
