memory size of C code

hi

after compilation of microblaze C code the log file says

---------------------------------------------- mb-size MB0/executable.elf text data bss dec hex filename

----------------------------------------------

My first question is

- Is it mean that "memory size = 2780 + 3441 = 6221 = bytes? "

Function of C code is that add 300 integers using array declaration. The execution stops after adding 250 integers. This is undesirable. I think this problem is comming from limited BRAM size.

Second question is

- How can we maximally utilize memory (BRAM) so that we can perform more powerful operations ?
