Dear All: I use a array in my program like this. int a[256]; But I found that, at program start phase, the system would initialize the array. Because my program storage is small, and it would take some time at power-on. This would not be good for ASIC test. Could someone give me a hint that how to remove the array initilzation action()? Best regards .....
the array as shown will not be initialized beyond the general RAM clear. erik
STARTUP.A51 contains the code that zeros out memory after reset. You could alter the file for your project to eliminate this initialization. Note that the C language spec requires that global variables without initializers be initialized to zero. (That's why the startup code does so.) Be sure that the other C code in your program does not rely on the system initializing everything to zero before removing the startup code. Non-zero C initializers are handled by the INIT.A51 code.
Because my program storage is small, and it would take some time at power-on. This would not be good for ASIC test. the time it takes is very limited, "discrete" initialization of even a few variables would take much longet. Erik
