from memory into registers to work with them there and storing back only the finished results. The relatively large general register set of the 8088 compared to its contemporaries assists this strategy. When there are not enough registers for all variables that are needed at once, saving registers by pushing them onto the stack and popping them back to restore them is the fastest way to use memory to augment the registers, as the stack PUSH and POP instructions are the fastest memory operations. The same is probably not true on the 80186 and
