Read value from array in assembly arm
WebFeb 26, 2024 · If you actually look at the ARM64 assembly for this example, you’ll see an madd instruction get used instead: madd x0, x0, x0, x8. This is a multiply+add in one instruction: it’s doing x0 = x0 * x0 + x8. ↩︎ These are just the 64-bit registers used by most integer instructions. WebTo move the first value from the array into eax, write the following: mov eax,[ebx] To change to the next value in the array, increment ebx by the size of each array element; in an array of dwords, this is 4: add ebx,4 To process an array using a base register, start with initializing a loop counter Also initialize the index register to 0.

WebLet's look at a simple example for ARM's design. Here is a machine language instruction: 1110 0001 1010 0000 0011 0000 0000 1001 When the processor is told to execute that binary sequence, it copies the value from “register 9” into “register 3.” But as a programmer, you'd hardly want to read a long binary sequence and make sense of it. WebThe offset to the PC is 0 (instead of 8), since the actual PC value is always the address of the current instruction + 8 - this is an effect of the early ARM processor pipeline which has to be preserved for compatibility.
