Abstract
A copy of data in a Host Computer is synchronized with a version located in Shared Memory in a Modular Development System (MDS). Whenever a change in one or more bits in a Line of Data in Shared Memory are detected, a MDS Line Dirty Flag is checked. If the Flag is not set, it is set and a message is sent to the Host Computer that the Line of Data is now dirty. Whenever the Host Computer receives this message for a Line of Data in its visible memory, it sends a request to the MDS to read that Line from Shared Memory and send it to the Host. Otherwise, a Host Line Dirty Flag is set. The Host Computer also sends a request to read a Line of Data when that Line of Data is scrolled onto a screen and the corresponding Host Line Dirty Flag is set.
