Abstract: Overall graphics performance in a computer graphics system is improved by an accelerated interface between high performance microprocessors and hardware adapters which is a combination of hardware and software and which is independent of specific computer languages. The interface was specifically designed for any hardware attached to a central processing unit (CPU) that does not enforce the order of memory accesses. The hardware supported process fools the CPU into thinking that the write and read are accessing the same address, thus guaranteeing that the order of the write and read are correct. In a first method, a hardware pseudo-address are created on the display adapter. When the software writes to the pseudo-address, the display adapter writes the data to the coordinate register. When the software reads from the pseudo-address, the display adapter returns the contents of the actual status address.
