What is the meaning of Small C library

Hi,

I used the debugger , and i could c the following:

In my design I have included an SDRAM controller with data width 16 bits and I have used it as main memory, though I have on chip memory for 50KB. ie; for CPU exception vector and reset vector.

Now I c that

int i;

PERF_RESET(PERFORMANCE_COUNTER_BASE);

PERF_START_MEASURING(PERFORMANCE_COUNTER_BASE);

PERF_BEGIN(PERFORMANCE_COUNTER_BASE, 1);

i=10;

i=i+1;

PERF_END(PERFORMANCE_COUNTER_BASE, 1);

PERF_STOP_MEASURING(PERFORMANCE_COUNTER_BASE);

these statements works fine with its address and data values, but when I include the

"perf_print_formatted_report((void *)PERFORMANCE_COUNTER_BASE,ALT_CPU_FREQ, 1,"Time");"

I get error from Nios build saying " Region needs to be 6684 bytes larger. ".

The design works well for lights example from altera, but when I include my code which is above; it gives the region needs to be larger, I understand that this is because of lack of memory, but I dont understand why there is not enough memory, as I have included SDRAM also.

In this I have not included the small C library option.

Thanks,

Anand
