Abstract
An uninterrupted data display method for a computer system having a system memory directly accessed by a processor, for preventing disrupted data display from transmission break is disclosed. The method is accomplished before the processor goes into a non-responding period due to an execution of an economical process. The method includes the steps of: (i) providing a data storage device having a depth for storing a period long of data. (ii) Comparing the period of said depth to the non-responding period, if the period of said depth is longer than the non-responding period, jump to step (iii), otherwise, to step (iv). (iii) Loading the period long of data from a system memory into the data storage device then jump to step (v). (iv) Detecting a synchronization pulse then jump to step (v), wherein step (v) is to be accomplished within a non-display period, and, (v) executing the economical process.
