optimize function's parameter in c (GCCarm)

i have limited RAM in my microController.(using arm gcc) i should write my code as efficient as possible. consider function blew :

int foo(uint32_t a , float b)
{
    .....
    return 0;
}

so i have two arguments a and b. now if i change the arguments to tow pointer to a and b is the the function takes less ram than the first function during execution :

int foo(uint32_t *a,float *b)
{
    ....
    return 0;
}

what if the arguments become String or array ( of int , float ....)?? any references would be grate. thanks
