First, architecture basics are detailed with information on the register sets, data types, and memory and instruction formats. Next, instruction set extensions are detailed, which include Intel® ...

If you cut your teeth on Z-80 assembly and have dabbled in other assembly languages, you might not find much mystery in creating programs using the next best thing to machine code. However, if you ...

Today we are very used to running a rich variety of operating systems and programs on our mobile devices, from Office on a Windows laptop to a game on our Android smartphones, we are accustomed to ...

When developing software for small microcontrollers, it is common to use assembly language in the final product. But there is still much value in prototyping the software and its algortihms in C. Here ...

Assembly language provides several instructions to facilitate conditional execution. We have discussed some of these instructions like jmp and loop in Chapter 9. Our discussion here complements that ...

Programming in assembly language -- getting down to the direct manipulation of bytes and even bits -- is gaining in popularity, according the latest ranking by TIOBE, apparently spurred by the ...

The microcontroller’s CPU reads program code from memory, one instruction at a time, decodes each instruction, and then executes it. All memory content—both program code and data—is in binary form: ...

David Letterman made the top ten list famous. [Creel] has a top ten that should appeal to many Hackaday readers: the top 10 craziest x86 assembly language instructions. You have to admit that the ...

The instructions a programmer writes when creating a program. Lines of code are the "source code" of the program, and one line may generate one machine instruction or several depending on the ...
