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 ...

Computer Architecture: Multithreading

Sun Niagara Multithreaded Pipeline 13 Tera MTA Fine-grained Multithreading 256 processors, each with a 21-cycle pipeline 128 active threads A thread can issue instructions every 21 cycles Then, why 128 threads? Memory latency: approximately 150 cycles No data cache Threads can be blocked waiting for memory More threads better ability to tolerate memory latency

14. Transistor Characteristics Lab - hunter.cuny.edu

Example: Suppose b=100 and Ib = 1.5 ma. How large is Ic? b = 100.; Ib = 1.5; Ic = b*Ib 150. Obviously the collector current is much larger than the base current. pnp Transistor When the two n regions are next to each other (as below) then one has a pnp transistor. It should be clear that one of the diodes in a transistor is in the forward ...

Electrons and Holes in Semiconductors - Chenming Hu

Figure 1–3 introduces a useful system of denoting the orientation of the silicon crystal. The cube in Fig. 1–3a repres ents the Si unit cell shown in Fig. 1–2 and each darkened surface is a crystal plane. The (100) crystal plane in the leftmost drawing in Fig. 1–3a, for example, is simply the plane in Fig. 1–2 closest to the reader.
