You see the datapath carries bits from registers straight into the arithmetic unit where calculations happen fast. It connects everything inside the processor so data flows without stops most times. And you watch how instructions pull values out then push results back in cycles that repeat. But sometimes paths cross and you need selectors to pick the right route for each operation. The whole setup moves numbers around like traffic on busy roads where one jam slows the rest. I think you notice how fetching from memory feeds directly into these lines before any math starts.
Perhaps the unit adds or subtracts based on what the control tells it to do right then. You follow one instruction through and see registers feed operands while the result writes back quick. Or maybe a shift happens instead if the bits need rearranging for the next step. I find it odd how simple paths handle complex tasks by chaining small moves together over and over. Now the buses link all parts so signals travel both ways without extra hardware cluttering things up. You try tracing a load command and it grabs data then routes it back to storage spots you picked earlier.
Also branches change the flow by swapping addresses into the program counter when conditions match. I see you wondering why some designs split this into stages for speed gains later on. But single paths work fine for basic chips where every action finishes in one go. Perhaps pipelining overlaps these moves so multiple instructions run at once without clashing much. The logic gates decide routes based on signals you send from outside the core. And you measure how long each pass takes because delays add up across long computations.
Registers act like holding spots that latch values until the next cycle kicks in strong. I notice the multiplexer picks between sources so only one value enters the unit at a time. You run a store operation and watch the path reverse from registers out to memory slots. Or the comparison unit checks equals and sends flags back to adjust the next address fast. This setup keeps everything moving even when data sizes vary across different jobs. Perhaps wider paths handle bigger numbers but they cost more power in the end.
You build understanding by following one bit stream through the entire chain from start to finish. I recall how feedback loops let results feed into new calculations without resetting everything each round. But external inputs mix in sometimes when devices push fresh numbers into the flow. The design stays efficient because paths reuse hardware for many different instruction types. And you test it by changing inputs to see outputs shift exactly as expected in each case.
