It turns assembly language into something, but the instruction set that the inner CPU, ALU, et al use was completely unknown. [Philip] walked us through their first line of attack, which was ...

There is no ALU chip. Or rather, there is; it’s just that an entire RISC CPU is implemented in basic logic chips and a whole lot of microcode on the ROM. It’s weird, yes, but it is cool.

We take a deep dive into the inner workings of mobile CPUs to explain why phones offer different levels of performance and battery life.

The CPU and memory work together to process instructions and run programs. There are different types of memory – volatile and non-volatile. The Arithmetic and Logic Unit (ALU) is where the CPU ...
