Hi ,
I am using ARM Cortex M4 . When I compile my code I get "No space in Execution region with .ANY selector matching section .const data .When I decrease the code size I am able to compile the code properly.I think I am overusing the data section which in my controller is 32KB.
I want to know where are all local variables stored in ARM KEIL IDE.Is it stored in Stack dynamically or stored in DATA memory Statically .
Thanks in advance
Regards, Dhanush
"So small that it is not realistically usable for automatic variable storage."
Yes, some processors has a stack just intended to handle a couple of levels of return addresses.
Real general-purpose processors on the other hand allows an arbitrary chunk of the RAM to be used as stack - or as multiple stacks in case of use with an OS that allows threads.
The 8051 is better suited for a language like Forth, with software-implemented push and pop operations. Most high-level procedural languages expects arbitrary access to an arbitrary amount of local variables.
I wonder if its designers ever envisaged it being programmed in anything other than assembler...?
