A sample UML class and sequence diagram for the Command design pattern. [3]In the above UML class diagram, the Invoker class doesn't implement a request directly. Instead, Invoker refers to the Command interface to perform a request (command.execute()), which makes the Invoker independent of how the request is performed.
Little Man Computer simulator. The Little Man Computer (LMC) is an instructional model of a computer, created by Dr. Stuart Madnick in 1965. [1] The LMC is generally used to teach students, because it models a simple von Neumann architecture computer—which has all of the basic features of a modern computer.
The program counter maintains the memory address of the next machine instruction to be fetched and executed. Therefore, a branch, if executed, causes the CPU to execute code from a new memory address, changing the program logic according to the algorithm planned by the programmer. One type of machine level branch is the jump instruction. These ...
National economies can be run from the top down, so to speak, in what is sometimes called a command economy or they can be run from the bottom up in what is sometimes called a free market. In the ...
The project consisted of 4 modules: an economic simulator, custom software to check factory performance, an operations room, and a national network of telex machines that were linked to one mainframe computer. [2] Project Cybersyn was based on viable system model theory approach to organizational design and featured innovative technology for ...
If the branch is not taken, the pipeline stays full. If the branch is taken, the instruction is flushed (marked as if it were a NOP), and one cycle's opportunity to finish an instruction is lost. Branch Likely: Always fetch the instruction after the branch from the instruction cache, but only execute it if the branch was taken.
A 1-bit saturating counter (essentially a flip-flop) records the last outcome of the branch. This is the most simple version of dynamic branch predictor possible, although it is not very accurate. A 2-bit saturating counter [1] is a state machine with four states: Figure 2: State diagram of 2-bit saturating counter. Strongly not taken; Weakly ...
