RE: execution time



The register itself is fast (one clock cycle to write) but the code
generated to load the values to store in the register may be 
several cycles.

Example 1:
*R_PAR0_CTRL_DATA = 33;
Approx time : 5 cycles

Example 2:
*R_PAR0_CTRL_DATA = variable1 | variable2;
Approx time : 10 cycles

Example 3:
*R_PAR0_CTRL_DATA = var1 % var2
Approx time: 100 cycles

Execution times can be found in the ETRAX 100LX programmer's
reference.

Hi,

Sorry this may sounds like newbie question (and really :-).

How much is the execution time of *R_PAR0_CTRL_DATA = anything | or |
something | else (or other register write)?

Thx
