Imsys IM1000

a Multimedia Platform for Java Applications

Applications
- Internet Appliances
- Integrated User Interface Units
- Java System on a Chip
- Printer, Copier and Multi-Function Peripheral Controllers
- Mobile Communicators
- Industrial Control Telematics

The IM1000 is a microcontroller suitable for Internet appliances, especially where memory size, component count, and power consumption must be kept low, while computationally intensive tasks must be performed. Its revolutionary architecture makes it efficient at both Java and real-time control, and it can do data communication as well as image processing and graphics. Large amounts of data can be transferred at very high data rates and in combination with the embedded software the microcontroller can act as a very efficient serial to TCP/IP converter.

IM1000 microcode in RAM and ROM
IM1000 hardware logic

• Java/C/C++, for complex, not very time critical tasks, for example User Interface, printer paper handling, etc
• Assembler, for medium complexity, medium speed applications, for example device drivers
• Microcode, for relatively small algorithms that are very time critical, for example image processing, real-time kernel functions or fast I/O
• Debug information available at all three levels.

Block Diagram

The diagram shows the main parts of the processor.

The microcode in the internal ROM and RAM controls the processor hardware logic and resources. The application program is in DRAM, external to the IM1000.

The architecture enables a realization of accelerated functions for CPU intensive tasks like TCI/IP checksum calculations, encryption etc.

A high-speed I/O bus connects the IM1000 to an external FPGA or CPLD for a flexible system design.
