The address of data[0]: 0x00605000. In fact, in ANSI C, the identifier for an array (in this case data) stands for the address of its first element. At run time this address will likely be in a base register.
You may be thinking that there has got to be an easier way to load a register from memory. At the machine language level there is not.
However, the assembler has features that make it easier
to write lw
and sw
instructions.
These are discussed in a later chapter.
Let us start on an example program.
The program is to
evaluate the polynomial
5x2 -12x + 97.
The value x is located in memory.
Store the result at location
poly in memory.
How many lw
instructions will be needed?
How many sw
instructions will be needed?
