ARM7 LPC2148 MICROCONTROLLER
[attachment=68392]
INTRODUCTION
An embedded system that has embedded software and computer hardware, which makes it a system dedicated for an application or specific part of an application or product or a part of a larger system. Today embedded systems found in many electronic devices like cell phones, digital cameras, calculators, microwave ovens, home security systems, washing machines, in medical equipments and many other devices/gadgets. Modern embedded systems are often based on Microcontrollers
ARM RISC ARCHITECTURE
ARM is a family of instruction set architectures for computer processor based on a 32-bit Reduced Instruction Set Computing (RISC) developed by Advanced RISC Machine (ARM) Ltd. The ARM architecture was originally conceived by Acorn Computers Ltd. in the 1980s. ARM processors are microprocessors and are widely used in many applications like mobile phones, hand-held gaming systems, calculators, and even in computer hard drives.
RISC (Reduced Instruction Set Computer) is a type of microprocessor architecture that utilizes a small highly-optimized set of instructions rather than a more specialized set of instructions often found in CISC (Complex Instruction Set Computer) architecture, where CISC designs involves very complex architectures including a large number of instruction sets, addressing modes, more computational power of the individual instructions, more specialized registers, and so on.
CONCLUSION
The architectural features and block diagram of the LPC2148 are explained. Pinning configuration, various ports and registers are explained such that we can easily interface the various modules such as GPS and GSM to the development board by writing the program.
