Instruction Representation 2 Review °MIPS defines instructions to be same size as data (one word) so that they can use the same memory (can use lw and sw). °Machine Language Instruction: 32 bits representing a single instruction R I opcode rs rt rd shamt funct opcode rs rt immediate °Computer actually stores programs as a […]

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

Distributed Systems: Distributed File Systems Anca Jurcut E-mail: anca.jurcut@ucd.ie School of Computer Science University College Dublin Ireland From Previous Lecture… Stateful File Service: The File Server keeps a copy of a requested file in memory until the client has finished with it. The principle advantage of stateful file services is increased performance. Example: Andrew
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

3 – combinational logic 1 Jan. 18, 2016 In lectures 1 and 2, we looked at representations of numbers. For the case of integers, we saw that we could perform addition of two numbers using a binary representation and using the same algorithm that you used in grade school. I also argued that if you
