R1EX24xxx series are two-wire serial interface EEPROM (Electrically Erasable and Programmable
ROM). They realize high speed, low power consumption and a high level of reliability by employing
advanced MNOS memory technology and CMOS process and low voltage circuitry technology. They
also have a 128-byte page programming function to make their write operation faster.
Note: Renesas Technology鈥檚 serial EEPROM are authorized for using consumer applications such as
cellular phone, camcorders, audio equipment. Therefore, please contact Renesas Technology鈥檚
sales office before using industrial applications such as automotive systems, embedded controllers,
and meters
Abstract. The main aim of this research is to improve communication between student and teacher by using the developing mobile information technologies. Implementing such technologies in education may help to develop learning environments to share the knowledge among students and increase their motivation to possible highest level. Based on mobile equipments used in daily life an online student announcement system has been developed which aims to provide sharing of documents and communication ways between students and teachers.
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.
The future satellite communication systems are re-
quired to support the higher transmission data rate
for providing the multimedia services by employing
the e鏗僣ient modulation method such as multi-level
QAM.
This is an interface program for flip flop emulation. At first pulse at the input pin the apropriate output will latch and at the second pulse will release. Very short and efficient program
This project features a complete JPEG Hardware Compressor (standard Baseline DCT, JFIF header) with 2:1:1 subsampling, able to compress at a rate of up to 24 images per second (on XC2V1000-4 @ 40 MHz with resolution 352x288).
Image resolution is not limited. It takes an RGB input (row-wise) and outputs to a memory the compressed JPEG image. Its quality is comparable to software solutions.
ecos RTOS 原理介紹和應用開發The design philosophy of eCos was to augment an open-source RTOS (which meant no
per-unit royalties) with source-level con?guration tools that would enable embedded developers
to scale their RTOS from hundreds of bytes to hundreds of kilobytes without needing to manu-
ally change a line of source code.
The use of hardware description languages (HDLs) is becoming
increasingly common for designing and verifying FPGA designs.
Behavior level description not only increases design productivity, but also
provides unique advantages for design verification. The most dominant
HDLs today are Verilog and VHDL. This application note illustrates the
use of Verilog in the design and verification of a digital UART (Universal
Asynchronous Receiver & Transmitter).
This document specifies a subset of the C programming language which is intended to be suitable
for embedded automotive systems up to and including safety integrity level 3 (as defined in the
MISRA Guidelines). It contains a list of rules concerning the use of the C programming language
together with justifications and examples.
This project developed in java leads us to realize a flight reservation system in order to emulate databases containing the structures for the flight and for the booking. These bases extend the List interface and implements additional search鈥檚 methods.
Two interfaces provide an access to this system. The first one reads and handles reservation request message from a terminal. The arguments are then processed throw a middleware interface that call the flight system methods. The second one, a Graphical User Interfaces (GUI) application using Swing Java Foundation Classes (JFC), offers a simpler access to the systems.
