  7. ARM (Advanced RISC Machine) • RISC FEATURES: • Reduced instructions • Pipelining • Load store architecture • Registers Reducedinstructions: • Utilizes a small, highly-optimized set of instructions.

  8. Pipeline organization : • 3-stage pipeline: Fetch – Decode - Execute • Three-cycle latency, one instruction per cycle throughput instruction i Fetch Decode Execute Fetch Decode Execute i+1 Fetch Decode Execute i+2 t t+1 t+2 t+3 t+4 cycle

  9. Load store architecture : • Does not support memory to memory data processing • Must move to registers before using them. • Process becomes much faster due to register access to process data. Registers : • Large general purpose register set. • Contains either data or address.

  10. ARM FEATURES: • Low power consumption • High code density • Hardware debugging technology • Reduced area of die. • Low cost memory device.

  11. LPC2148 : LPC 2148 microcontrollers are based on a 32/16-bit ARM7TDMI-S processor.

  12. ARM 7TDMI-S ARM –Acron Risc Machine (Now Advanced Risc Machine) • T – The Thumb 16 bit instruction set. • D – On chip Debug support. • M – Enhanced Multiplier • I – Embedded ICE hardware to give break point and watch point support. • S- Synthesizable

  16. ZIGBEE MODULE • Created by Zigbee alliance based on IEEE 802.15.4 standard. • Designed for control and automation. • Allows wireless two way communication • Low cost, low power consuming technology for WPAN’s.

  17. SPECIFICATIONS • Typical range 50m • Data rates of 250 kbps (@2.4 GHz), 40 kbps (@ 915 MHz), and 20 kbps (@868 MHz). • Fully hand-shaking protocol. • Multiple topologies • Addressing space of up to: 65,535 networks

  22. TYPES OF ANTENNAS

  23. KEY BENEFITS • Ultra-low power consumption • MAC sub layer specifies four security services: • maintains a list of trusted devices. • Data encryption. • Frame integrity. • sequential freshness.

  24. APPLICATIONS • Industrial and Commercial • Monitors • Movement Sensors • Automation • Personal Healthcare • Patient monitors • Remote Diagnosis • Data loggers • Building Automation • Security • Lighting • Fire and Safety systems • Automotive • Service controls • Inventory tracking

  25. RFID MODULE • RFID MODULE convert radio waves returned from the RFID tag into a form that can be passed on to Controllers. • RFID read range of this module will vary from approx10mm to 30mm • This Firmware has the following Functions: • Read Tag-ID • Send Tag-ID in ASCII Format through the Serial Interface

  26. To enable wireless identification, the RF subsystem consists of two components: • RFID tags which are small electronic devices that are affixed to objects or embedded in them. • RFID readers, which are devices that wirelessly communicate with tags to identify the item connected to each tag.

  27. TAG CHARACTERISTICS • Major characteristics of tags include: •  Identifier format, • Power source • Passive • Active • Operating frequencies,

  28. TAG READER COMMUNICATION • Tag-reader communication is achieved by using a common communications protocol between the tag and the reader. • Communication Initiation : • Tags and readers can initiate RF transactions in two general ways: • Reader Talks First (RTF). • Tag Talks First (TTF).
