Abstract:
A method for transferring data within a system memory directly onto a host bus within a microcomputer system, the data within the system memory being retrieved and stored through a system memory bus, a data path of the system memory bus being twice as wide as a data path for the host bus, the host bus providing a communication link between the system memory and a system processor, the method comprising the following steps:(a) selecting a first set of data bits to be placed on the system memory bus;(b) transferring a first half of the data bits selected in step (a) onto the host bus, the transfer being done directly from the system memory bus to the host bus without transmission through a memory control unit;(c) transferring a second half of the data bits selected in step (a) onto the host bus, the transfer being done directly from the system memory bus to the host bus without transmission through a memory control unit;(d) selecting a second set of data bits to be placed on the memory bus;(e) transferring a first half of the data bits selected in step (d) onto the host bus, the transfer being done directly from the system memory bus to the host bus without transmission through a memory control unit;(f) transferring a second half of the data bits selected in step (d) onto the host bus, the transfer being done directly from the system memory bus to the host bus without transmission through a memory control unit.
