Hi.  When a program in a 32-bit machine accesses a 8-bit data, is it slower than accessing a 32-bit data (since the bus is 32-bit).   If it is slow, can you tell me how much slower?     Thanks...

That would be highly dependent on your particular CPU and its configuration. I suggest writing a small program and timing it!
