Systems, methods, and devices for buffer handshake in video streaming

A device comprising:

• a buffer configured to store a designated number of lines of a video frame included in video data;
• and
• a controller comprising one or more processors configured to:
• determine a plurality of store parameters associated with a store operation and a plurality of fetch parameters associated with a fetch operation for the designated number of lines, wherein the plurality of store parameters and the plurality of fetch parameters identify whether a fetch unit or a store unit should be stalled;
• implement a store operation in the buffer for at least some of the designated number of lines based on the plurality of store parameters;
• and
• implement a fetch operation from the buffer for at least some of the designated number of lines based on the plurality of fetch parameters.

A system comprising:

• a host processor and memory configured to execute a software application and graphics driver;
• a buffer configured to store a designated number of lines of a video frame included in video data;
• a controller configured to
• determine a plurality of store parameters associated with a store operation and a plurality of fetch parameters associated with a fetch operation for the designated number of lines, wherein the plurality of store parameters and the plurality of fetch parameters identify whether a fetch unit or a store unit should be stalled;
• implement a store operation in the buffer for at least some of the designated number of lines based on the plurality of store parameters;
• and
• implement a fetch operation from the buffer for at least some of the designated number of lines based on the plurality of fetch parameters a display device configured to display a result of the fetch operation.
