Thanks for replying! However, what I want to happen is for the product to still be a 32-bit integer. My problem is that GCC takes uses the upper 16 bits of 'a' and 'b' as well as the lower bits. If you multiply the upper 16 bits of 'a' with the lower 16 bits of 'b', then you still get a number that is contained within 32-bits, and hence it affects the product that is added to the accumulate value. Is there anyway to instruct GCC to only use the lower 16 bits in the multiplication? I am aware of the smlabb instruction (16x16+32->32) but I want to replicate the functionality of that instruction using the mla instruction (32x32+32->32).
