The memory model determines which

default memory type will be used for

function arguments, automatic variables,

and declarations that include no explicit

memory type.

Since our project is very simple, we will

choose the Small memory model. In this

model, all variables, by default, reside in

the internal data memory of the 8051

system. Variable access in this memory

modelisveryecient.
