Multi-threaded Rasterization for Display Latency Reduction

The patent segments the rasterization workload by creating multiple worker threads (first worker thread, second worker thread, etc.) that can independently process different content elements simultaneously. The compositor thread divides rasterization requests among these worker threads, enabling parallel processing and eliminating the single-thread bottleneck that caused delays and missing content.

The patent implements preliminary action by having worker threads pre-process and prepare content for display before the compositor thread needs it. The worker threads can begin rasterization work in advance, and the compositor thread retrieves already-prepared content, eliminating the waiting period while maintaining accuracy through the coordinated thread architecture.

The patent segments the CPU workload by distributing rasterization tasks across multiple worker threads instead of concentrating all work in the main thread. This segmentation balances the CPU load across available cores, preventing overload and delays while maintaining a relatively simple multi-threaded structure that doesn't significantly increase system complexity.
