Designing withProgrammable Logicin an Analog WorldProgrammable logic devicesrevolutionized digital design over 25years ago, promising designers a blankchip to design literally any functionand program it in the field. PLDs canbe low-logic density devices that usenonvolatile sea-of-gates cells calle ...

In the past decade, the size and complexity of manyFPGA designs exceeds the time and resourcesavailable to most design teams, making the use andreuse of Intellectual Property (IP) imperative.However, integrating numerous IP blocks acquiredfrom both internal and external sources can be adaunting ch ...

  This application note describes the implementation of a two-dimensional Rank Order filter. Thereference design includes the RTL VHDL implementation of an efficient sorting algorithm. Thedesign is parameterizable for input/output precision, color standards, filter kernel size,maximum horiz ...

This application note covers the design considerations of a system using the performance features of the LogiCORE™ IP Advanced eXtensible Interface (AXI) Interconnect core. The design focuses on high system throughput through the AXI Interconnect core with F MAX  and area optimizat ...

  Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptabl ...

讨论、研究高性能覆铜板对它所用的环氧树脂的性能要求，应是立足整个产业链的角度去观察、分析。特别应从HDI多层板发展对高性能CCL有哪些主要性能需求上着手研究。HDI多层板有哪些发展特点，它的发展趋势如何——这都是我们所要研究的高性能CCL发展趋势和重点的基本依据。而HDI多层板的技术发展，又是由它的应用市场——终 ...

This document provides practical, common guidelines for incorporating PCI Express interconnect layouts onto Printed Circuit Boards (PCB) ranging from 4-layer desktop baseboard designs to 10- layer or more server baseboard designs. Guidelines and constraints in this document are intended for use on b ...

a8259 可编程中断控制 altera提供 The a8259 is designed to simplify the implementation of the interrupt interface  in 8088 and 8086  based microcomputer systems. The device is known as a programmable interrupt controller.  The a8259 receives and prioritizes up to 8 interrupts,  ...

  Accurate measurement of the third order intercept pointfor low distortion IC products such as the LT5514 requirescertain precautions to be observed in the test setup andtesting procedure. The LT5514 linearity performance ishigh enough to push the test equipment and test set-up totheir lim ...

This application note discusses a variety of approaches for interfacing analog signals to 5V powered systems. Synthesizing a "rail-to-rail" op amp and scaling techniques for A/D converters are covered. A voltage-to-frequency converter, applicable where high resolution is required, is also presente ...
