C++ is widely used in the software industry. Some of its application domains include systems software, application software, device drivers, embedded software, high-performance server and client applications, and entertainment software such as video games. Several groups provide both free and proprietary C++ compiler software, including the GNU Project, Microsoft, Intel, Borland and others.

This paper will discuss the design of an asynchronous FIFO,Asynchronous FIFOs are widely used in the computer networking industry to receive data at a particular frequency and transmit them at another frequency. An asynchronous FIFO has two different clocks: one for read and one for write.

This control is another extension to the now standard and widely used ListView control. I have included some of the more common features: shaded columns, column sorting (with data type), but the real addition is the FILTERBAR features of the header. This implementation eliminates all of the work of dealing with the filter messages and item filtering by incorporating it into the control. This could have been implemented as delegates, but we create controls to do the work for us, don t we? I would like to thank Carlos H. Perez since a lot of the implementation came from examples he set with his ListViewEx control.

For a programming language, Fortran has been around a long time. It was one of the first widely used 鈥渉igh-level鈥?languages, as well as the first programming language to be standardized. It is still the premier language for scientific and engineering computing applications. The purpose of this handbook is to describe the latest version of this language, Fortran 90. This chapter gives some history of the development and standardization of Fortran and describes the notation used to specify the syntax of Fortran 90.

Abstract: Transimpedance amplifiers (TIAs) are widely used to translate the current output of sensors like photodiode-to-voltagesignals, since several circuits and instruments can only accept voltage input. An operational amplifier with a feedback resistor fromoutput to the inverting input is the most straightforward implementation of such a TIA. However, even this simple TIA circuit requirescareful trade-offs among noise gain, offset voltage, bandwidth, and stability. Clearly stability in a TIA is essential for good, reliableperformance. This application note explains the empirical calculations for assessing stability and then shows how to fine-tune theselection of the feedback phase-compensation capacitor.

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 acceptable. For example, if the circuit powers up in an invalid state, or the circuit is in an extreme working environment and a glitch sends it into an undesired state, the circuit may never get back to its normal operating condition.
