In chip-multiprocessors (CMPs), the number of cores and the issue width of each core presents an important design trade-off to balance the amount of TLP and ILP between multi-threaded and single-threaded applications. This paper explores the trade-off between issue-width of the cores and the number

for feature sizes of 0:8m, 0:35m, and 0:18m. Performance results and trends are expressed in terms of issue width and window size. Our analysis indicates that window wakeup and selection logic as well as operand bypass logic are likely to be the most critical in the future. A microarchitecture that simplifies

as many cores as possible we show that these applications can be run as efficiently and with comparable power consumption on a chip-multiprocessor (CMP) with fewer, but wider-issue cores. This is attributable to their inherent ILP and the fact that fewer cores result in less performance and power

Total integrated scatter from surfaces with arbitrary roughness, correlation

overhead will increase in the future as processors use more aggressive speculation and wider issue widths [9]. In this paper, we present an innovative method for power reduction which, unlike previous work that sacrificed flexibility or performance, reduces power in high-performance microprocessors without

grayscale value of the two images are the location x = [x y] T, where x and y are the two pixel coordinates of a generic image point x. The image I will sometimes be referenced as the first image, and the image J as the second image. For practical issues, the images I and J are discret function (or

Besides the very successful concept of tree-width (see [Bodlaender, H. and Koster, A. (2007) Combinatorial optimisation on graphs of bounded treewidth. These are special issues on Parameterized Complexity]), many concepts and parameters measuring the similarity or dissimilarity of structures

This paper aims to develop vector controlled permanent magnet linear synchronous motor (PMLSM) based on simplified space vector pulse width modulation. Mathematical models of PMLSM&SVPWM presented. The present PWM technique does not involve any sector identification and considerably reduces

achievable flow rate

The present study dealt with the wall static pressure of a rectangular curved duct with angle of turn 90 ° at all four faces with various locations. The normalized wall static pressure distributions at the top, bottom, inside and outside surfaces of the C-duct are drawn in the form of contours at three different air velocities, Uav = 20m/s, 40m/s and 60m/s respectively. These iso-bar contours indicate towards the presence of secondary flow in the duct in the form of a pair of contra-rotating vortices for all the three air velocities.
