Example embodiments of the present disclosure provide techniques for dividing bitmaps into tiles and processing the tiles concurrently using multiple tile engines. Data compression algorithms may be adapted so that the algorithms can be concurrently processed by multiple data slice engines. The algorithms may be further adapted so that the concurrent outputs for each stage may be passed to the next processing stage without delays or dead cycles. The reduction or elimination of delays or dead cycles may result in a lower latency.

Example embodiments of the present disclosure provide techniques for improving the rendering and management of client desktops and the subsequent transmission to the remote client. The techniques may minimize the movement of frame data within the server, the amount of data to be compressed, the amount of data transmitted over the network, and the amount of data to be decompressed. Various embodiments are disclosed for merging rendering functions and encoding functions onto the same chip so that frame data does not need to be transferred, calculation of a tile-based checksum for determining which tiles have changed from frame to frame, the dropping of tiles waiting to be transmitted if network bandwidth or decode speed is limiting the transmission and an equivalent tile in a subsequent frame is available to replace it, and the transfer of the frame buffer into the chip from an external GPU using one of three modes.

Disclosed are methods and systems for tracking which data tiles have changed within an image frame. In an embodiment, each cell of a tile change list buffer may contain a frame number and updated when a tile is received from encoder. The frame number may be used as a base pointer for a particular frame buffer. When a frame is decoded, the contents of the tile change list buffer may be copied from the current tile change list buffer to the next buffer. This process may reduce memory traffic because the unchanged tile data does not have to be copied from frame to frame.
