Hi sir how do i calculate machine cycle for my TMS320C6745
Arun Kumar R,
Its depend upon the crystal value you are using and the PLL configuration.
For Example :
Assume this following board
Crystal Used : 24Mhz
PLL configured for : 300Mhz
PRE_DIV is set to divide by 1
PLLM is set to 24. Multiplier Value = PLLM + 1., i.e, multiply by 25
POST_DIV is set to 1. Divider Value = RATIO + 1. post-divide by 2
note: Refer attached PLL functional block diagram to apply above calculation.
Machine cycle = 1/sysclk
