145Execution speed on ADuC 703x
- Nov 6, 2007Hello,
I'm developping SW for ADuC 7033/7034 (high precision analog
measurement for vehicle battery sensor). I need fast code execution,
although the fastest the µC can run is 20,48 MHz ; so I need a strict
control of some routines that I code in ASM, or in C but I check the
assembly. The problem is that until now I have not found the good rule
to compute the execution time of the instructions. In this mode the
THUMB mode is faster, due to the FLASH which is 16 bits wide only.
The ARM documentation specifies a calculation mode with a number of N,
S and I cycles (or C-cycles, but there is no Floating Point
Anybody has a good rule to compute the execution time of the
instructions in THUMB mode ?
