he paper intcoduces the hardware structure and the softWare of an integrated circuit testing system which is composed by 8031 single chip computer. The settings of each port of the two 8255 chips and C port state are explained.
As the design size keeps growing and the feature size keeps scaling down in integrated circuits, the effects of short channel and interconnector are major factors in determining the performance, so that timing convergence has become one of the most intractable problem for designers.
The current progress of computer system technology is described according to system performance of different types of computers, development of system architecture, integrated circuits and high density package technology as well as system software.
The denseness and performance index of Integrate Circuit (IC) have been enhanced rapidly in geometric series according to Moor's Law. Such extraordinary growth has made enormous contributions to the development of whole IT industry.
With the rapid development of electronic and integrate circuit technology, digital signal processing has been widely applied in various field, like speeching and graphing processing, communication, multimedia.
The design and manufacture of integrate circuit now is not the task of integrate circuit manufacturer with the micro electronic technology developing. The system designer would like to design Application Specific Integrated Circuit (ASIC) themselves to meet the requirement of client for multiplicity and time.
Physical defects have always played an important role in integrated circuit (IC) yields, and the design sensitivity to these physical elements has continued to increase in today's nanometer technologies.
The designs ensure highly stable operation up to microwave frequencies, offer an electronically adjustable current-voltage characteristic, and can be implemented as a monolithic integrated circuit.
Near field zone of an integrated circuit exposed to an electromagnetic wave in a waveguide
The electromagnetic field distribution in the vicinity of an integrated circuit was calculated based on a numerical solution of the problem of electromagnetic wave diffraction on a model metal-dielectric structure in a waveguide tract.
A flux of high-velocity microparticles, transmitted through a thick steel obstacle in the regime of superdeep penetration, also passes through the case of an integrated circuit (IC) situated behind this wall and produces damage of the IC chip.
Aminochalcone 18, which has an IC50 value of 0.24 μM, was the most potent compound.
In vitro enzyme inhibition studies have identified three inhibitors (14, 16, 23) of the falcipains with one (14) showing dual activity against both falcipain-2 and falcipain-3 and IC50 values of 6.6 and 29.4 μM, respectively.
In this study, we find that prodigiosin could effectively inhibit the proliferation of human pancreatic cancer cells H8898 in a dose-and-time-dependent manner, with an IC50 of 75μmol according to the results of MTT and cell proliferation assays.
Additionally, (2) also inhibited the proliferation of human erythroleukemia cancer cell line K562 with IC50 value of 49.1 μg/mL.
1 exhibited significant inhibitory activity against the human DNA topoisomerase I (hTopo I), the cancer cell lines BEL-7402 and MCG-803, with the IC50 values 12.0, 6.5, and 8.0 μg/mL, respectively.
A kind of correlator with double count systems, composed of IC (Integrate Circuit) chips is developed.
Intellectual Property (IP) reuse methodology has been widely used in Integrate Circuit (IC) design.
