Configuration/Program Method for Altera Device
Configure the FLEX Device
You can use any Micro-Controller to configure the FLEX device–the main idea is clocking in ONE BITof configuration data per CLOCK–start from the BIT 0The total Configuration time–e.g. 10K10 need 15K byte configuration file•calculation EQUATION–10K10* 1.5= 15Kbyte–configuration time for the file itself•15*1024*8*clock = 122,880Clock•assume the CLOCK is 4MHz•122,880*1/4Mhz=30.72msec
Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical EQUATION quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."
PID calculations for the _pid structure *a. This function uses the positional form of the pid EQUATION, and incorporates an integral windup prevention algorithim. Rectangular integration is used, so this function must be repeated on a consistent time basis for accurate control.
describes the most common terms used in radarsystems, such as range, range resolution, Doppler frequency, and coherency.
The second part of this chapter develops the radar range EQUATION in many of its forms. This presentation includes the low PRF, high PRF,search, bistatic radar, and radar EQUATION with jamming.
《Prolog Programming in Depth》:
In this book, we emphasize practical Prolog programming, not just theory. We
present several ready-to-run expert system shells, as well as routines for sorting,searching, natural language processing, and even numerical EQUATION solving.
We also emphasize interoperability with other software. For example, Chapter 5 presents techniques for reading Lotus spreadsheets and other special file formats from within a Prolog program.
