Your code has two problems: You don't know whether the interrupt that increased SysTickMajor happened before or after you read the timer value into time. Operations on 64-bit values are not atomic on a 32-bit system. So the value for SysTickMajor could be updated by the interrupt between reading the two 32-bit words.
WebThe CYCLECOUNTER register in IAR Embedded Workbench are useful to check how many cycles that are consumed for the running code. The CCSTEP register is handy and useful when checking the number of cycles during the last performed C/C++ source or assembler step. Set breakpoints and note the CCSTEP value for the sqrt functions:
