A method for synchronizing two of more graphics processing units. The method includes the steps of determining whether the phase of a first timing signal of a first graphics processing unit and the phase of a second timing signal of a second graphics processing unit are synchronized, and adjusting the frequency of the first timing signal to the frequency of the second timing signal if the first timing signal and the second timing signal are not synchronized.

Method for synchronizing graphics processing units

A method for testing synchronization between a first graphics processing unit coupled to a second graphics processing unit. The method includes detecting whether an incoming synchronization signal has been received, determining whether the incoming synchronization signal is received from one of the first graphics processing unit, the second graphics processing unit and an external synchronization signal, and indicating on a control panel one of a first and second synchronization input/output ports on one of the first graphics processing unit and the second graphics processing unit as an input port and the other one of the first and second synchronization input/output ports as an output port, if the incoming synchronization signal is received from the one of the first graphics processing unit and the second graphics processing unit.

Method for testing synchronization and connection status of a graphics processing unit module

Systems and methods for providing on-demand memory management. In response to a mapping request from a device driver or other program, a first portion of the memory is mapped to one or more virtual addresses in a first region of a virtual memory space so that it can be directly accessed by the CPU. In response to an unmapping request the first portion of the memory is unmapped. Mapping and unmapping requests may be made at any time.
