ABSTRACT:
A method for performing buffer copy operations in a personal computer system utilizing paged memory mode architecture and having a cache memory. The contents of a first buffer are read into a microprocessor register and simultaneously written into a cache memory. The first buffer is then read again and written to a second buffer, with the actual data values being obtained from the cache memory. This method avoids excessive wait states associated with changing memory pages from the first buffer memory address to the second buffer memory address for each data value.
