Benchmarking was done on Pandora at stock speed - 600 MHz
Benchmark consists of 60000 calls to scaler function with following parameter combinations:
Source width (pixels): (varying) 305 - 320
Source height: 240
Source alignment (modulo 16): (varying) 0 - 15
Results:
|Total |Time per |Calls per |Cycles per
