The quantization errors that affect the practical implementation of a real-time digital system using fixed-point arithmetic are examined. A digital simulation scheme written in the C programming language suitable for use on a microcomputer is presented to help analyze these quantization errors. The digital simulation scheme presented is an interactive program that includes a graphics module that allows the user to change the characteristics of system components to show their affect on overall system performance. The simulation is used to analyze both a digital filtering and a computer controlled system. The results obtained from the digital simulation are compared to results obtained experimentally using actual real-time systems.$CLK $CLK: ;Assembly Interrupt Routine ;When the P-clock interrupts, the interrupt is acknowledged ;and service begins at $CLK. After the registers are ; saved, (integer and floating point) control is transfered ;to the address stored in $ ADDRanbsp;...
