Decoding most of the infrared signals can be easily
handled by PIC16C5X microcontrollers. This application
note describes how this decoding may be done.
The only mandatory hardware for decoding IR signals
is an infrared receiver. The use of two types is
described here. Both are modular types used often by
the consumer electronics industry. The first type
responds to infrared signals modulated at about
40 kHz. The second responds to non-modulated infrared
pulses and has a restricted range. The hardware
costs of each approach will be less than two dollars.

The ARM architecture is not a static constant but is being developed and improved to suit the
applications required by today’s consumer devices.
The MIPS32® 4KEm™ core from MIPS® Technologies is a member of the MIPS32 4KE™ processor core family. It is a
high-performance, low-power, 32-bit MIPS RISC core designed for custom system-on-silicon applications. The core is
designed for semiconductor manufacturing companies, ASIC developers, and system OEMs who want to rapidly integrate
their own custom logic and peripherals with a high-performance RISC processor. It is highly portable across processes, and
can be easily integrated into full system-on-silicon designs, allowing developers to focus their attention on end-user
products. The 4KEm core is ideally positioned to support new products for emerging segments of the digital consumer,
network, systems, and information management markets, enabling new tailored solutions for embedded applications.
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,

Introduction

The ARM Cortex -A8 microprocessor is the first applications microprocessor in ARM!ˉs
new Cortex family. With high performance and power efficiency, it targets a wide
variety of mobile and consumer applications including mobile phones, set-top boxes,
gaming consoles and automotive navigation/entertainment systems. The Cortex-A8
processor spans a range of performance points depending on the implementation,
delivering over to 2000 Dhrystone MIPS (DMIPS) of performance for demanding
consumer applications and consuming less than 300mW for low-power mobile devices.
This translates into a large increase in processing capability while staying with the
power levels of previous generations of mobile devices. Consumer applications will
benefit from the reduced heat dissipation and resulting lower packaging and integration
costs.

The software and hardware development fields evolved along separate paths through the end of the 20th century. We seem to have come full circle, however. The previously rigid hardware on which our programs run is softening in many ways. Embedded systems are largely responsible for this softening. These hidden computing systems drive the electronic products around us, including consumer products like digital cameras and personal digital assistants, office automation equipment like copy machines and printers, medical devices like heart monitors and ventilators, and automotive electronics like cruise controls and antilock brakes.
Embedded systems force designers to work under incredibly tight time-tomarket, power consumption, size, performance, flexibility, and cost constraints.
Many technologies introduced over the past two decades have sought to help satisfy these constraints. To understand these technologies, it is important to first distinguish the underlying embedded systems elements.
SQLite is a software library that implements a self-contained, serverless, zero-configuration, transactional SQL database engine.
SQLite is the most widely deployed SQL database engine in the world. It is used in countless desktop computer applications as well as consumer electronic devices including cellphones, PDAs, and MP3 players. The source code for SQLite is in the public domain.
