The MGDP Mobile Vehicle incorporates the following hardware:

The MGDP Mobile Vehicle movement is controlled by an operator using the standard RC (Radio Controlled) joystick device.

While in motion, the MGDP Mobile Vehicle JStamp controller reads obtains GPS PVT (Position/Velocity/Time) information from the GPS Receiver across a standard RS-232 serial port connection. It then transmits this information in real-time across a second serial port to the Internet across the wireless connection device to the back-end Server that persists this information. The back-end server returns indicators that tell the JStamp controller whether the siren, headlights or flasher should be turned on or off.

JStamp uses the powerful new aJ-80 native Java processor from aJile Systems This provides fast and efficient Java instruction execution, plus a small memory footprint - 2 to 3 times denser than code for 32-bit RISC machines. The aJ-80 includes a microprogrammed real-time Java thread manager so that a typical RTOS is not needed. It includes Java threading primitives implemented as atomic instructions, a priority-based preemptive scheduler, extremely fast context switching and interrupt response. The aJ-80 supports multiple application execution through “multiple JVMs”. Applications execute in a deterministic, time-sliced schedule. Each application has its own thread management and event handlers.

JStamp is ready for serious work with 512 KBytes of SRAM and 512 KBytes of Flash (2 MBytes on JStamp+). Code can be executed from flash or SRAM. JStamp has five 24- mA I/O pins plus seventeen 8-mA pins (some of which also serve the UART and SPI functions). JStamp includes a SPI interface for easy peripheral and I/O expansion. The Jstamp development station adds hardware support for RS-232 serial I/O, and - very soon plug- on JSimm modules for Dallas 1-Wire network, CAN network, IrDA, RF, graphic LCD, analog I/O, power relays, and more. Of course, many current simmstick modules are JSimm compatible.

JStamp uses a JTAG interface for programming and debugging with aJile's JEM Builder and Charade development tools. JTAG pods are available from Systronix and Xilinx. Software requires Windows 98/NT/2000 and a PC parallel port.

aJile networked Java direct execution processors combine several innovative technologies to efficiently, safely, and robustly execute Java in wide variety of low-power embedded systems. The aJ-80 that is used in the JStamp is derived from the ground- breaking JEM™ Java processor that was first developed at Rockwell Collins. Incorporating direct execution of more than 99% of all Java bytecodes, and with an embedded thread manager that eliminates the need for an external real-time operating system (RTOS), the aJ-80 is the perfect Java processor for low-cost, low- power embedded applications.

aJile technologies include:

The MGDP Web Service is built upon the following hardware:

The MGDP Client Workstation is built upon the following hardware:

While in motion, a custom MGDP Java application uses the Chaeron Java GPS Access Library (a cross-platform GPS library that runs on almost any device supporting Java) to obtain GPS events that contain PVT (Position/Velocity/Time) data in real time. The application uses the kSoap library (a very small footprint web services library, designed for embedded devices) with a custom-written HTTP Transport handler to invoke a Position Tracking web service using SOAP across the internet (over a wireless link) to send it’s PVT information (along with detailed GPS NMEA data) to the back end service. The SOAP response from the Position Tracking web service is parsed to retrieve indicators that that determine whether the siren, headlights or flasher should be turned on or off.

The Mobile Unit uses the following software on the JStamp/aJile processor:

The back-end J2EE-based web service tracks and persists the Mobile Unit PVT (Position/Velocity/Time) information using a JAX-RPC SOAP interface running on the Apache Tomcat servlet engine. The data is persisted to a relational database using EJB components. Web Services interfaces are provided to retrieve the current Mobile Vehicle position information along with an interface that can be invoked to remotely control whether the Mobile Vehicle siren, headlights or flasher should be turned on or off. A WSDL definition is provided which defines the MGDP Web Services interfaces.

The MGDP Web Service (J2EE) Server Software uses the following software::

The MGDP Client Mapping Application uses a JAX-RPC SOAP interface to the MGDP Web Service to discover the current and historical position of the Mobile Vehicle. It then displays this information, using Swing or a Browser interface, on a moving map display. Images for the map display are obtained either from static scanned map images (.jpg) or can be obtained in real-time from the TerraServer Web Service (a publicly available web service implemented using Microsoft’s .NET) which provides USGS Aerial Satellite maps for the whole of the continental USA. The MGDP client application also provides to select the source of the map (TerraServer or Scanned), the type of map (Aerial satellite photo, Topographic or Relief) and the map resolution (from 1 meter up to 16 km per pixel). The Client Mapping App also allows the remote user to turn on/off the Mobile Vehicle siren, headlights and/or flasher.

The MGDP Client Mapping Application uses the following software:

Various tools were used on all platforms (Mobile Vehicle, Web Service Server and Client Mapping Application) to develop, debug and test the MGDP software.

Some of the primary MGDP Development tools included:

The power of computing is moving beyond the desktop. The Internet is bringing a new generation of smart, distributed, networked applications to an incredible new array of consumer devices: smart phones, smart cards, PDAs, set-top boxes, information kiosks -- even gas pumps.

aJile Systems, Inc. is at the forefront of this evolution. Founded by a team of technologists who developed the world's first direct-execution processor for the Java™ platform, aJile develops and markets a family of microprocessors and IP cores that deliver high-performance, low-power and low-cost execution to embedded applications. aJile's innovative processors have been used by Mitsubishi Electric, and many other system developers who are leading the revolution.

aJile Systems was formed in July 1999 by a group of technologists from Rockwell Collins, Sun Microsystems, and Centaur Technologies. The principals of aJile Systems share a common belief that the rapid proliferation of Java technology, the Internet, and recent advances in CMOS process technology are extending the Java paradigm beyond the desktop and server. By providing a family of low-power networked single-chip Java microprocessors and IP cores, which includes a real-time kernel, aJile's founders are helping to bring the Java revolution to a wide variety of handheld, mobile and consumer appliances.

While still at Rockwell Collins, aJile's principals led a team responsible for the development of the JEM1, the world's first direct execution Java microprocessor, which achieved its first silicon in July, 1997. JEM technology enables low-power embedded applications to be programmed entirely and directly in Java and at the same time to achieve the efficiency and performance of comparable conventional embedded processors programmed in C.

aJile licensed Rockwell's JEM technology and is developing the aJile family of processors for low-power embedded networked applications.
