Imsys Developer IDE

A visual integrated development environment, optimized for Imsys microprocessor based products. It handles a mix of Java, C, and assembler code. The tools included are source code editor, on-line manuals and help system, C-compiler, assembler, linker, loader and trace/debug tools.

The figure above shows a snapshot of how Imsys Developer looks on the screen.

An application project is created, the programs compiled, files are collected and transferred to the target and the target application is run and debugged, using the Imsys Developer.

As is indicated in the figure, while target debugging is performed, a part of the target memory can be displayed as a bitmap in Imsys Developer, e.g. to simulate a customer target LCD, which is perhaps not yet available or connected.

High and Low level programming

Imsys Developer can be used to program applications on all levels. Complex tasks are programmed in Java or C. Time critical parts are programmed in Assembler, i.e. at the machine instruction level.

Downloading to the Target and Debugging

When an application has been compiled and linked, in Imsys Developer, it is downloaded to the target system. Imsys Developer is then used to trace or debug the application. Debugging is provided on source code levels, both in C and Java, as well as on machine code level, with all the usual debugging features.

If Java is used, usually Java class files are collected and transferred to a file system in the target. Also data files of different type can be included in the project and transferred.

Features

Java, C source and Assembly-level debugger

Breakpoints, Single-step - Step throught the code at Java, C or Assembler level. Code disassembly - Switch between debugging at Java, C or machine code level. Watch expressions - Update complex expressions and function calls without stopping program execution. Java call stack - Displays the top of the Java call stack. Register window - Control and manipulate registers and flags. Stack window - Displays the top of the processor stack. Hex memory dump - Window for display of the content of memory addresses. STDIO window - Displays Output (printf) and input from host PC keyboard. Bitmap view - Display of the target memory as a bitmap. Terminal window - Online target debugging through Ethernet or serial line.

Moose™ RTOS

Real-time operating system that provides threads to be used in C or automatically included as a base for the Java system. Timing is based on the Cjip hardware timeslot, with a frequency of 16 kHz. Semaphores are supported, typically used by applications to lock common resources during manipulation.

Board specific drivers with Java and/or C APIs

No in circuit emulator

Advanced simulator that allows application software to be developed and executed without the need of a hardware target.

MIDP

Mobile Information Device Profile (MIDP) is a Sun Microsystems package of standardized Java APIs to create user interface. MIDP provides the core application functionality required by today's standard for mobile information devices (MIDs) such as phones and entry level PDAs.
