| titleOfInvention | Bus control method and apparatus in direct memory access control unit |
| abstract | The present invention relates to a method and apparatus for controlling a bus in a direct memory access (DMA) control unit in a computer system. The bus control apparatus of the present invention uses an external master bus when a bus is used as an exclusive point in a DMA. A control logic unit for generating a control signal to use the controller, channel allocating units for receiving a control signal transmitted from the control logic unit and generating a signal for controlling the occupancy or non-occupancy of a bus, the control logic unit and the It characterized in that it comprises a master (Master) for setting the type of occupancy of the bus based on the control signal received from the channel allocator. In the bus resource control method of the present invention, a process of generating a first control signal for setting whether the bus is exclusively occupied or not occupied, and a second control signal to set the bus occupancy type regarding whether the bus is used in a plurality of cases. Generating a second control signal that can be used by an external master even when the bus is used as an exclusive point in the DMA; and receiving a control signal to set an occupancy mode of the bus. Characterized in that made. According to the present invention, various forms of DMA occupying a bus can be used to more efficiently use bus resources. |
