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® ...

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 ...

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 ...

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: ...

The ARM processor is popping up everywhere. From Raspberry Pis, to phones, to Blue Pill Arduino-like boards, you don’t have to go far to find an ARM processor these days. If you program in C, you ...

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 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 ...

This week, [Al Williams] wrote a great thought piece about whether or not it was worth learning an assembly language at all anymore, and when. The comments overflowed, and we’re surprised that so many ...
