Presented byDivyashree N C(4GW09TE011) Mahiya Aqsa(4GWO9TE023)Manasa B H(4GW09TE024) Maya M Gadagkar(4GW09TE025)
UNDER THE GUIDANCE OFMs. Hussna johar R BAsst. Prof, Dept of TE
GSSSIETW, Mysore
Overview
• To develop a palm computer which consumes less power • Does not emit any radiations above
the specified threshold.• This provides higher order security
The peripherals interfaced are• Bluetooth• Wi-Fi• Global Positioning System (GPS)• Liquid Crystal Display (LCD)• Keypad
Introduction
Atom Palm Computer (APC) is a portable computer that has features of a hand held computer like laptops.
Problem statement
• Need to geographically locate a soldier in military areas.• In earlier technologies, mobile
phones were used to obtain information about location.
REQUIREMENTS
HARDWARE
APC uses• Atom Processor• System Controller Hub (SCH)• DDR2 technology (1600x2 MbPS)• Embedded Controller
REQUIREMENTS
SOFTWARE• Windows XP or above for the host
computer• Windows 7 for the device APC• Visual Studio v2010
INTERFACES
The interfaces mentioned in the above Block Diagram are listed below
1. Front Side Bus (FSB) 2. Universal Serial Bus (USB) 3. Low Voltage Differential Signalling (LVDS) 4. Parallel ATA (PATA) 5. Serial Digital Input Output (SDIO) 6. Low Pin Count (LPC) 7. General Purpose Input Output (GPIO) 8. Serial Peripheral Interface (SPI) 9. General Purpose Input Output (GPIO) 10. Inter- Integrated Circuit (I2 C)
• ATOM Processor – Intel Z520• System Controller Hub (SCH) – Intel US15W• Embedded Controller – Renasas H8S/2117R
MERITS
• Enhanced computing speed.• Supports all windows based
applications. • Operates well in high altitude and
damp heat(+50°C) conditions.
APPLICATIONS
• Geographical location tracing. • Sending of reports for data to
communication centres.
This device has used Atom processor with System controller hub and embedded controller on VC++ platform for LCD brightness control and enabling/disabling of peripherals (Bluetooth, GPS and keypad)
FUTURE ENHANCEMENT
To provide more advantageous features, the Atom Processor Z520 can be replaced by Z530 and DDR3 technology can replace DDR2 technology.
