Latest Patents

Sun Tjen Fam's latest patents include groundbreaking systems and methods aimed at improving the development of image processing intensive programs. One of his notable inventions is a shader profiler, which describes techniques to non-intrusively monitor the run-time performance of shader programs on a GPU. This invention allows for the profiling of shader program execution by sampling data during the execution of compiled code on the GPU. It determines the execution duration of sequences of instructions within the code and assesses the relative latency of these instructions. This process ultimately maps binary instructions to source code, providing insights into the execution time of each source code instruction in a shader per draw call.

Another significant patent is the shader program profiler, which also focuses on non-intrusive monitoring of shader programs on GPUs. This invention configures GPU-based hardware threads to run in parallel without interfering with the execution environment during shader program execution. This configuration enables accurate characterization of the run-time behavior of an application program's shader operations.
