Has anyone written a routine that will tell how many cycles a given 60000 instruction will need to execute? I want to pass this routine the hex code (1 to 5 words) for a certain instruction, and I would like it to return the number of cycles it will require. The returned value may be an upper bound, or up to 3 separate values if the execution time depends on some condition codes. If anyone knows of such a routine, please let me know. --Mark A.
