5 – sequential logic 1 Jan. 25, 2016 Sequential Circuits All of the circuits that I have discussed up to now are combinational digital circuits. For these circuits, each output is a logical combination of the inputs. We have seen that these circuits can do arithmetic and other operations. But these circuits are not powerful […]

C/Assembler Arithmetic and Memory Access Overview °C operators, operands °Variables in Assembly: Registers ° Addition and Subtraction in Assembly °Memory Access in Assembly Review C Operators/Operands °Operators:+,-,*, /,%(mod); •7/4==1, 7%4==3 ° Operands: • Variables: fahr, celsius • Constants: 0, 1000, -17, 15.4 °Assignment Statement: Variable = expression • Examples: celsius = 5*(fahr-32)/9; a = b+c+d-e;
Logical and Shift Operations Overview °Logical Instructions ° Shifts Bitwise Operations (1/2) °Up until now, we’ve done arithmetic (add, sub,addi ), memory access (lw and sw), and branches and jumps. °All of these instructions view contents of register as a single quantity (such as a signed or unsigned integer) °New Perspective: View contents of register
