#104610 - Optimisation Responding to: ???'s previous message |
Remember that it takes a lot more code to access XDATA than direct RAM. Therefore you may be able to significantly reduce your code size by moving your most-frequently-used variables from XDATA into DATA.
You can easily identify your most-frequently-used variables with uVision by using the Code Browser, and sorting by the 'Uses' column. In one fairly large project, this saved a couple of Kbytes of code space! Disabling Integer Promotions can also help a lot. The benefits of all this do, of course, depend upon the nature of the existing code - YMMV. |
