Memory map and register boundary addresses

WebIn 32-bit processors, memory addresses and Registers are 4-byte wide and it becomes very efficient to access them in 4 byte size. These addresses are aligned in 4 byte boundary. So if current memory location address is 0x00000000 and then it is incremented by 1, it becomes 0x00000004. Websize, allowable mapping boundaries, and register functionality depends on the device. It should be the first consideration to remap the memory. Memory information is included …
