A Tool for Analyzing Assembly Language Projects in Embedded Systems

Abstract The paper presents some of our recent results in the field of computer emulation for supporting and enhancing the educational processes. The ATmega 328P micro-controller emulator has been developed as a set of emuStudio emulation platform extension modules (plug-ins). The platform is used at the Department of Computers and Informatics as a studying and teaching support tool. Within the Assembler course, currently, the Intel 8080 architecture and language is briefly described as a preliminary preparation material for the study of Intel x86 architecture, and the Intel 8080 emuStudio emulator module is used here. The aim of this work is to explore the possibility to enrich the course by introducing a more up-to-date and relevant technology and the ATmega is the heart of Arduino – a popular hardware and software prototyping platform. We consider the options to make the process of studying the assembly language principles more attractive for students and using the ATmega AVR architecture, which is broadly deployed in embedded systems, seems to be one of them.

Dose Imaging

We have assembled an image processing system for use with our high resolution STEM for the particular purpose of working with low dose images of biological specimens. The system is quite flexible, however, and can be used for a wide variety of images.The original images are stored on magnetic tape at the microscope using the digitized signals from the detectors. For low dose imaging, these are “first scan” exposures using an automatic montage system. One Nova minicomputer and one tape drive are dedicated to this task.The principal component of the image analysis system is a Lexidata 3400 frame store memory. This memory is arranged in a 640 x 512 x 16 bit configuration. Images are displayed simultaneously on two high resolution monitors, one color and one black and white. Interaction with the memory is obtained using a Nova 4 (32K) computer and a trackball and switch unit provided by Lexidata.The language used is BASIC and uses a variety of assembly language Calls, some provided by Lexidata, but the majority written by students (D. Kopf and N. Townes).
