Digital Logic And Computer Design Link
Now, things get emotional. The ALU is the “calculator” of the CPU. It takes two binary numbers and, based on a few control lines, decides whether to add them, subtract them, AND them, OR them, or compare them.
Eventually, you need to orchestrate all these pieces. You need a (registers + ALU) and a controller (a finite state machine). The controller reads instructions from memory, decodes them, and tells the ALU what to do. digital logic and computer design
And yet, from that perfect determinism, we get emergent chaos: bugs, glitches, metastability, race conditions. And from that chaos, we get software that feels alive. Now, things get emotional
There is only hierarchy. From transistors to gates, gates to flip-flops, flip-flops to registers, registers to datapaths, datapaths to processors, processors to systems. Eventually, you need to orchestrate all these pieces
