The labels used for the direction of the steepest descending path are shown on the ... the direction of the steepest descending path. (a) shows the criterion used when determining order of steepest descendent path when there is more than one possible path; that is, the pixel has...

... if the deadline of the message at the head of each trip can be met, the deadlines of all other messages can also be met. Denote the delay of the message at the head of (k +1) th trip as D k+1 .AscanbeseenfromFigure ... Area on the Maximum Throughput. As shown in (13), the maximum throughput that can be achieved is determined by the deadlines of messages, the travel time between th...

... The go al of prefetching through the multithread- ing mechanism is to have the geometry already in memory by the time it is needed. But the threads will occupy some of the main memory and this ... 4.454. Another example that demonstrates the benefits of rule- based prefetching is show n in Figure 3. We demonstrate three different requests of a client as a snapshot. With the help of th...

The integration of IP blocks into the compiled datapaths poses a different set of problems than stitching together IPs to form a system-on-chip; though, instead...

... of the echoes, the dispersivity of the spring bends the echoed impulses into chirps. Broadly speaking, the impulse response of a spring can be thought of as two series of these dispersive echoes ... The group delay has a maximum at f C . The second set of echoes is present over the whole audio band, but at much lower amplitudes than the lower-frequency echoes. This set of chir...
