Hi guys, I’m an electronics and communication final year student. I’m struggling to understand microprocessor working. Can someone explain what a memory mapped I/O and port mapped I/O is in simple terms? Any YouTube videos recommendation would be of great help.|
May 10, 2023 at 6:53 pm #2315Bro in simple words memory mapped I/O uses RAM addresses to access input and output devices. Input and output devices are allocated memory addresses. While in port mapped I/O, separate I/O addresses are allocated for accessing input and output devices. Pordi physics se tension mat le.padh padh ke microprocessor jhagda kardega tujse.
May 10, 2023 at 6:55 pm #2316Memory mapped IO is straightforward. Port mapped IO is little complex.Spend more time on memory mapped IO and concepts related to it in your textbooks and class notes. Don’t spend too much time online. You’ll get confused. Focus. All the best fam!
May 10, 2023 at 6:56 pm #2317For memory mapped I/O they use RAM addresses. Easy to implement in hardware. For port mapped I/O they use separate I/O addresses. Hard to implement in hardware. Microprocessor just adds on to the complication in your life. Focus on basics first dude, rest will follow.
