Abstract:
The use of the microprocessor and/or computer for the control of lenses, deflectors, stigmators, camera, gun, accelerating voltage, vacuum system, etc. in the transmission microscope has resulted in improved and simplified operation of the microscope without a consequent sacrifice in the operating flexibility of the TEM. Based on years of experience with electron microscopists, the basic ergonometric design of the microprocessor/computer controlled instrument remains unchanged since the microscopist still has to stradle the microscope in order to operate the stage and apertures.

Speed is one of the important issues that generally customers consider for selecting any electronic component in the market. Speed of a microprocessor based system mainly depends on the speed of the microprocessor which in turn depends on the memory access time. Accessing on chip memory takes more time than accessing off-chip memory. Because of these, designers of memory system may find cache compression as an advantageous method to increase speed of a microprocessor based system, as it increases cache capacity and off-chip bandwidth.
