In this paper, we present a performance comparison of existing clocked dynamic comparators. As delay is directly correlated with the submicron scaling, we investigate the performance of the above comparators in terms of delay and Power-Delay Product (PDP). PDP gives the average energy dissipated by the comparator for a single comparison. Simulation results using Mentor Graphics revealed better ...

This paper illustrator* tho methodology of the CMU Design Automation System by presenting, an automated design of the PDP-8/E data palhs from a functional description. This automated clnsign (using synthesis techniques) is compared both to DECV, implementation and the Intersil single chip implementation.

The paper proposed a new design for implementing semi-static flip-flop for low power and high performance applications. In this work, comparative analysis of six existing flip-flop designs along with the proposed design is made. The proposed design has better power, delay and PDP than the existing architectures. All simulations are performed on TSpice using BSIM models in 130 nm process node. T...

PDP (Protocol Diaqnostic Program) is a proqram for analyzing think-aloud protocols of subjects solvinq elementary physics problems *. Two versions of PDP implement models of problem solving behaviour at novice and intermediate levels of expertise. In order to compare the behaviour of the models with think-aloud protocols of subjects, PDP is equiped with a think-aloud component, which communicat...

A UNIX operating system together with a complete user environment has been implemented on the VAX-11/780 computer manufactured by Digital Equipment Corporation. The VAX-11/780 system provides 32-bit addresses and data. It uses the same input/output devices and the PDP-11 family and is controlled through a console computer which can be remotely accessed. Additionally, the VAX-11/780 is priced ne...

Posturography is routinely used to qualitatively assess one of the cardinal symptoms of Parkinson’s disease – postural instability. While most measures of balance control are derived from displacement of the center of pressure there is evidence that such control is more likely to be velocity-based. We performed static posturographic tests (eyes open and eyes closed) during quiet standing in nar...

Service function chaining (SFC) is an indispensable technique for Internet service providers to efficiently manage their networks. However, SFC poses requirements of additional processing time functions (SFs) and increased routing owing detoured paths. In this paper, we introduce the use a programmable data plane (PDP) reduce times in SFC. We first classify existing PDP-empowered schemes analyz...

After decades of research and development, plasma displays are finally beginning to appear in the commercial and consumer markets. Following a short review on the basic principles of direct and alternating current plasma displays, we present a summary of the status of color plasma displays. Plasma display panels (PDPs) have finally achieved luminance and efficiency values on par with hi-definit...

T his special issue of Computer is about recent efforts to produce T hardware and software architectures that support artificial intelligence (Al) applications. The earliest computer design to support Al processing was the implementation of Lisp on the PDP-6 computer and its successors, the PDP-10 and PDP-20, all made by the Digital Equipment Corporation. The half-word instructions and the stac...
