#58076 - how to reduce data memory usage |
can anyone tell me how to reduce the data meory usage?
i have 2 similar projects(they have almost the same function routines and variables declared,they use the same microcomputer),but one uses only 61.2 byte data memory and the other use 102.2 byte data memory,the figure is get from keil c51's compiling message: first one :Program Size: data=61.2 xdata=..... second one: Program Size: data=102.2 xdata=... i carefully declared my global variables in Xdata memory,so i wonder where the additional 60 bytes data memory coming from? i really want to reduce the memory usage in project 2,but i don't know where to start? |
