text: diffrence between hardwired & microprogrammed control? computer organisation & architecture hardwired systems are made to perform in a set manner, implemented with logic, switches, etc. between any input and output in the system. once the manner in which the control is executed, you can not change the behavior of the system.  microprogrammed systems are centered around a computer of some sort, often a microcontroller in small systems, that controls the system using a program. input is sent to the computer, and the program determines what should be done with the input to come up with an output. so the processor is between the input and the output, rather than a direct link between the input and output.  the vesatility of the microprogrammed system far exceeds the hardwired system. the systems can also be considerably smaller. the size of a complex microcontroller can be quite a bit smaller that a bunch of logic and switches for the same functionality.  this what you were looking for?
