Data Sheet  
Microprogram Controller  
August 19, 2008  
instruction 15 the test condition is passed, no branch is taken; the microprogram counter register  
furnishes the next address. When the loop is ended, either by the count becoming zero, or by  
passing the conditional test, the stack is POP’d by decrementing the stack pointer, since interest in  
the value contained at the top of the stack is then complete.  
As one example, consider the case of a memory search instruction. As shown in Figure II, the  
instruction at microprogram address 63 can be Instruction 4 (PUSH), which will push the value 64  
onto the microprogram stack and load the number N, which is one less than the number of memory  
locations to be searched before giving up. Location 64 contains a microinstruction which fetches  
the next operand from the memory area to be searched and compares it with the search key.  
Location 65 contains a microinstruction which tests the result of the comparison and also is a TWB  
for microprogram control. If no match is found, the test fails and the microprogram goes back to  
location 64 for the next operand address. When the count becomes zero, the microprogram  
branches to location 72, which does whatever is necessary if no match is found. If a match occurs  
on any execution of the TWB at location 65, control falls through to location 66 which handles this  
case. Whether the instruction ends by finding a match or not, the stack will have been POP’d once,  
removing the value 64 from the top of the stack.
