aJile Systems provides complete
solutions for embedding Java performance into smart mobile devices,
wireless consumer appliances, industrial control, wireless remote
sensing, and automotive communication devices over the Internet. At
aJile, a complete solution means that our Java™ direct execution
processors come with a specifically tailored peripheral set, the
associated 100 % Java-based runtime software and tools, and the
required product-specific APIs. The figure below illustrates a complete
Java solution based on the aJile family of processors:

networked Java direct execution processors combine several innovative
technologies to efficiently, safely, and robustly execute Java in wide
variety of low-power embedded systems. Our key technologies include:
- Direct JVM bytecode execution
Software interpretation is a drag on performance. Java is the native
instruction set for all of aJile's microprocessor and microprocessor
cores. With more than 99% of Java bytecodes microprogrammed in
hardware, aJile MPUs deliver unparalleled Java execution with a memory
footprint that is 2- to 3-time more compact than similar 32-bit RISC
applications.
- Microprogrammed real-time Java thread manager
aJile MPUs don't require an extra RTOS software layer. The on-chip
real-time thread manager performs priority-based preemptive scheduling
with extremely fast context switch times -- less than 1us.
- Multiple application execution
Embedded system designers enjoy the security and reliability of
multiple JVMs when they develop aJile-based products. Discrete software
applications are memory- protected with selectable code & data
sharing. Each application has its own thread manager and event
handlers. Applications can also implement unique memory management and
garbage collection policies.
- Custom instructions for application specific optimizations
aJile's flexible architecture enables embedded system designers to
optimize their Java applications. Using extended Java bytecodes and
standard programming tools, designers can implement custom instructions
that deliver 5X to 10X performance improvements.
- Embedded programming tools
System designers can use commercial Java IDEs to easily build and debug
their embedded applications on aJile MPUs and MPU cores.
aJile MPUs and MPU IP cores include a complete portfolio of
peripherals. Timers and interrupt controllers, memory and memory
controllers, 2D and 3D graphics engines, multimedia codecs, and a
variety of communication interfaces are all integrated into the aJile
architecture.
- Integrated power management
Mobile applications can go Java with aJile's comprehensive power
management strategies, including sleep and standby modes that maximize
battery life.
