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

Latches and Flip-Flops

edge triggered D-CE flip-flop of Figure 11-27(c). Assume Q begins at 1. a) First draw Q based on your understanding of the behavior of a D flip-flop with clock enable. b) Now draw the internal signal D from Figure 11-27(c), and confirm that this gives the same Q as in a).

• Edge-triggered: Read input only on edge of clock cycle (positive or negative) • Example below: Positive Edge-Triggered D Flip-Flop • On the positive edge (while the clock is going from 0 to 1), the input D is read, and almost immediately propagated to the output Q. Only the value of D at the positive edge matters. D C S C R D Clock Q Q
