Computer Architecture: Branch Prediction

How to Handle Control Dependences Critical to keep the pipeline full with correct sequence of dynamic instructions. Potential solutions if the instruction is a control-flow instruction: Stall the pipeline until we know the next fetch address Guess the next fetch address (branch prediction) Employ delayed branching (branch delay slot) Do something else (fine-grained multithreading)

CMOS Power Consumption - ECE:Course Page

Ways to reducing power consumption Load capacitance (C L) ⌧Roughly proportional to the chip area Switching activity (avg. number of transitions/cycle) ⌧Very data dependent ⌧A big portion due to glitches (real-delay) Clock frequency (f) ⌧Lowering only f decreases average power, but total energy is the same and throughput is worse 1.00 1 ...

MOSFET transistor I-V characteristics

Depletion Mode NMOSFET • Depletion mode FETs have a channel implanted such that there is conduction with V GS=0 • The operation is the same as the enhancement mode FET, but the threshold voltage is shifted •Vt is negative for depletion NMOS, and positive for depletion PMOS VGS n+ n+ VS VDS n+ p

Flow Chart/Process Flow Diagram - University of North ...

Aug 26, 2015 · A Flow Chart (also known as a Process Flow Diagram or Process Map) is a diagram of the steps in a process and their sequence. Two types of flow charts are utilized in quality improvement. A high-level flowchart, outlining 6-10 major steps, gives a high-level view of a process. These flowcharts display the major blocks of activity, or the major ...
