Tips and Tricks for CMU Programming
The following section is intended to give hints for efficient programming and to point out frequent
mistakes that may impair the system performance.
1. Avoid Frequent DLL Swapping
Many CMU function groups use the same commands enabling program parts to be reused in different
contexts. As a consequence, commands may be repeated several times within a program that
addresses several function groups. The CMU is designed for multi-mode operation, however, changing
from one function group to another generally absorbs system capacity for loading new software
modules. It is therefore advisable to group the commands so that the number of function group swaps
is minimized.
Instead of GSM900MS_Sig: <Setting_A> write GSM900MS_Sig: <Setting_A>
GSM400MS_Sig: <Setting_A> GSM900MS_Sig: <Setting_B>
... ...
GSM900MS_Sig: <Setting_B> GSM400MS_Sig: <Setting_A>
GSM400MS_Sig: <Setting_B> GSM400MS_Sig: <Setting_B>
