| CProfiler | Profiler The role of the profiler is to report the average processing speed (# of samples processed per time unit) during the last N seconds. We want to calculate the average processing speed efficiently (with O(1) complexity, without allocations, and as lightweight as possible). The problems with this are that we have variable-sized frames and SMA requires fixed-size chunks. To efficiently perform this calculation a ring buffer is employed. The idea behind the ring buffer is that each chunk of the buffer is the average speed of 10ms worth of samples. The ring buffer is initialized with fixed size (N * 1000)ms / (10ms) chunks. Within each chunk a weighted mean is used to calculate the average speed during those 10ms. Each frame will contribute a different number of samples to each chunk, the chunk speed is then weighted based on how many samples are contributed at what frame speed. As the chunks get populated the moving average is calculated. When the buffer is not entirely full the cumulative moving average algorithm is used and once the buffer is full the simple moving average algorithm is used |
