I wanted to try out an opencl code with sin and tan inverse. I wanted to know the number of cycles that these trignometric functions take and also how accurate they are compared to the PC implementation
Any help is very much appreciated…
Table 7.1 in the OpenCL specification (http://www.khronos.org/registry/cl/specs/opencl-1.1.pdf) details the accuracy of single-precision math functions that is guaranteed by OpenCL. There is a similar, unnumbered, table in section 9.3.9 for double-precision functions. The performance will vary depending on platform, and could be data dependent, so it would be best to measure it on your platform of interest with data of the desired range and distribution.
