to the compiled code and is not available to any linked-in user written assembly code. In this case, the contents of FSR could be stored in a temporary variable before it is changed into assembly language code and restored upon leaving the assembly language code. Another way the PIC microcontroller can implement a data stack is to use temporary variables and access them directly. For the assignment statement example above, the operations would be:

This method gets very complex when statements that have more than one stack entry are left on the stack during execution. The two types of statements that best come to mind are ones that use array elements and those that call subroutines or functions that require more than one input parameter. In these cases, the data is evaluated and left on the stack for later operation. Adding an array element read to the example statement:

would result in the post x heap shown in Fig. 3.5 and the stack operations:

Push Push Push Execute Push Execute D 4 C[ * B +
In this example, the order of operations would be to push D onto the stack, followed by 4. When the Push C[ operation was encountered, the previous element (the 4)
A = B + (C[4] * D) + B C[ 4 * D
Figure 3.5 Post x heap with array element pushed onto the stack.
SOFTWARE DEVELOPMENT TOOLS
would be popped off the stack and used as the index into array C. Once C[4] was evaluated, it would be pushed onto the stack and the operation would continue as before with the result left on the stack. Many subroutines and functions have multiple parameters passed to them. For the function:
int Func(int varA, int varB)
a calling assignment statement could be:
A = B + Func(C[4], D);
which would generate the post x heap shown in Fig. 3.6 and the stack loading:
Push Push Push Call Push Execute D 4 C [ Func B +
The stack is executed through similarly to the previous example, but when the Func call is encountered, the two previous values are left on the stack and then Func is called with them as local variable arguments. In Func, the two arguments are referenced according to their position relative to the top of the stack; the rst parameter is one position below the stack top while the second parameter is the stack top. If Func was:
Int Func(int varA, int varB) { varA = varA + 1; return varA * varB; } // end Func
A = B + Func(C[4], D) + B C[ 4 Func D
Figure 3.6 Post x heap showing a function call with an array element as an argument.
TOOLS OVERVIEW
the actual compiled code for the function could be:
Func: ; varA = varA + 1 Push StackTop - 1 Push 1 Execute + Pop StackTop - 1 ; return varA * varB Push StackTop - 1 Push StackTop Execute * return
; ; ; ;
Push varA as the new stack top Push 1 onto the stack Pop varA and 1, add, push result Pop stack top and store in varA
; Push varA as the new stack top ; Push varB as the new stack top ; Pop varA and varB, multiply, push ; result
In the calling code after the initial call statement, the rst stack item would be popped off and saved and the next two would be popped off and discarded. The saved value would then be pushed onto the stack and execution would continue. Another way of doing this would be to pop the new top value off the stack and place it as the rst stack element before the call. Once this is done, any other values could be popped off the stack and discarded. The code making this call and popping off the unneeded stack elements would look like this:
Push Push Call Pop varA varB Func StackTop - 2
; Put result in the rst parameter ; position Pop BitBucket ; Get rid of second parameter (varB) ; Result of Func is the top stack element
When you look at actual code produced by a compiler, you will probably see deviations from the strict stack operations outlined in this section. Optimizing code in the compiler causes these deviations. For example, statements like:
A = B + (C * (4 * 2));
should be executed as:
A = B + (C * 8);
with the stack operations looking like:
