Abstract
A data communications system for a computer for transferring data between the memory of the computer and one or more peripheral devices without requiring an interrupt context switch. The data communications system includes a number of specialized registers in the central processing unit of a computer, a computer memory, a data storage location associated with one or more peripheral devices, and a bus connecting the data storage location to the memory. The specialized registers in the central processing unit are dedicated exclusively to processing data transfers between the memory and the data storage location associated with the peripheral devices. Data transfers between the computer memory and the data storage location associated with the peripheral devices are made under the control of the central processing unit with the use of the special registers without the execution of an interrupt context switch.
