22. 21 ARM Core Family Products There are 5 product families of ARM processor cores:  ARM7 Thumb Family  ARM9 Thumb Family  ARM9E Family  ARM10E Family  ARM11 Family  SecurCore Family

23. 22 ARM Core Family Products (contd) The 5 product families can be categorized into 3 system categories: 1. Embedded Real-time systems Cores 2. Open Platforms Cores 3. Secure Applications Cores

24. 23 ARM Core Family Products (contd)

25. 24 ARM Core Family Products (contd) Our group particularly interested in 2 arm cores from the selected arm-core table They are ARM920T and ARM922T

26. 25 ARM Core Selection Consideration Factors Fast speed A member of Thumb technology family Have a cache (Instruction/Data) Have Memory Management Unit (MMU) Samples of application that may use this particular processor. The availability of the microcontroller products that contain these processors. Have embedded JTAG debug capability

27. 26 Overview of LCD Technology Passive Matrix (STN) Active Matrix (TFT) AddressingMultiplexDirect/Active ResolutionLowHigh Power Consumption LowHigh CostLowHigh

28. 27 LCD requirements for Smartphone 1. Viewing purposes/colored display Email and web browsing Applications Display cheapest call costs and bills 2. Touch Panel Interface Alternative to a “mouse” Dial without keypad

29. 28 LCD Models Considered: 1. Sharp TFT LCD touchscreen: Model: “LQ05703DC02” 320x240 QVGA cost: US$455.05 2. Hitachi LCD touchscreen: Model: “SP10Q003-T” 320X240 STN Colour graphic display cost: AU$261.75 Direct interface from “DragonBall MX1” Not Chosen: Too expensive and hard to get. Chosen: Much cheaper than Sharp and availability from many distributors. Reason: Need only an inexpensive LCD as our group intends to use it for proof of design and it interfaces with our microprocessor

30. 29 POTS/Modem Requirement: Make phone call Modem / Fax Caller Id, Call Waiting Answering machine Billing detection / Call Duration Video Conference (Optional) Downloadable Ring Tone (Optional) To comply with Australian standards Fulfil telephone safety requirement

31. 30 Pots (Plain Old Telephone Service) Basic Design Micro Phone Speaker Duplex Coil Hook Switch Keypad and tone generator Ringer Line Interface Wall Tip Ring

32. 31 Modem, Fax and Caller Id Modem is a peripheral device which enable transmitting digital data through telephone line. Modulation Demodulation Telephone Line Analog SignalDigital Signal Analog Signal Digital Signal

33. 32 Modem, Fax and Caller Id (cont) Fax machine components Photo Diode Sensing Array to read data in the entire line Modem to send data through telephone line

34. 33 Modem, Fax and Caller Id (cont) Caller Id is the identification of the originating subscriber line. Two types of Caller Id Caller Id Type I Caller Id Type II

35. 34 Modem, Fax and Caller Id (cont) Caller Id mechanism: Caller Id Information received as analog signal Modem Decode the analog signal into standard 8 bit ASCII character with ‘0’ start bit and ‘1’ stop bit Processor drives display on the screen

36. 35 Telephone Safety Requirement Telephone regulations require high voltage barrier between telephone line side (high voltage)and digital device side(low voltage) Three kinds of implementation Transformer Optical Isolation DAA technology

37. 36 DAA Technology Philosophy Isolation of high voltage section and low voltage section capacitively Basic Design of DAA technology System Interface Microprocessor Isolation Barrier Line Interface DAA Phone Line High VoltageLow Voltage

38. 37 DAA Technology (cont) Why using DAA ? –Isolation barrier used is lighter, smaller, cheaper and has better densities compare to transformer –Can fulfill wide variety of telephone application such as FAX, Modem, Caller Id, etc –Provides Programmable line interface to meet global line requirements

43. 42 Australia Telephone Standards Put Australia phone standards Such as voltage Time gap between ring Time of ringing, etc

44. 43 Connectivity Options Need to allow connectivity for external I/O devices such as keyboards, printers, scanners etc Also need to allow for network/LAN connectivity Trade-off between flexibility and complexity/price

45. 44 External I/O Devices USB ports – almost all types of I/O devices nowadays connect via the USB port(eg- printers, keyboards etc) Standard serial port – Unlikely to be used, but is there if necessary

46. 45 External I/O Devices (cont) Infrared interface – Convenient for wireless keyboards and mice Our design will probably directly support a PS/2 keyboard interface through the use of an AVR chip

47. 46 Network Connectivity Main requirements are flexibility and high bandwidth (>56kbps) Standard 10/100BaseT ethernet/LAN interface PCMCIA interface for wireless LAN

48. 47 Network Connectivity (cont) Fallback option of external modems/routers/hubs that can be connected via the ethernet or USB ports Considered built-in ADSL modem but this doesn’t seem feasible

49. 48 Connectivity Design Challenges Ideally would like to directly support as many network and I/O devices/options as possible External devices such as cable/ADSL modems take up physical desk space

50. 49 Connectivity Design Challenges (cont) Writing/porting device drivers for external devices is also a problem However, for cost and complexity reasons, convenient features like in built ADSL are not going to be supported

51. 50 USB requirements/USE: More detailed description… USB port allows technologies ie connecting a shopping device scanner to order shopping items online, ADSL modem for fast internet connection and paying bills online..
