A Comparison of Meansort and Quicksort

Description: The main purpose of this project is to compare a new sorting method- Meansort with its preceding sorting method- Quicksort. Meansort uses the mean value for each key to determine the partition of the file, but Quicksort selects at random. Experiments proved that in some ways Meansort is superior to Quicksort but is still not perfect since it always needs a mean value for each key. This project implements these two methods and determines the situations under which each of these methods outperfor… more

Mini-ADA Compiler Project

Description: The Ada language is one of the most controversial topics in computer science today. Ada was originally designed as a solution to the software maintenance problems encountered by the United States Department of Defense[2], and as a multi-purpose language to be used particularly in an embedded computer system[7]. Never before has a project been undertaken. The Ada language does not simply entail the construction of a new compiler or a new language definition, it is this and a great deal more.

Notes on the SWTPC MP-N Calculator Interface and the Calc-1 Program

Description: This interface was bought to perform floating-point arithmetic and for its function capabilities such as SIN, COS, and e^x. My application required an integer truncation function that is not performed by this calculator, so i wrote a small assembly language subroutine to do it. A potentially irritating problem is that the calculator chip does not automatically convert to scientific notation if the numbers become too big to display in floating point. The control program must keep track of the di… more

A Method for Applying Scientific Subroutine Package in Microprocessor

Description: The scientific subroutine package is one of the most important parts of the software for the scientific industry. By now, most big computers have scientific packages, but applying such a software package in microprocessors requires consideration of the microprocessor's facilities, such as limited main memory, slow execution time, and only a few small registers. In any scientific package, the trigonometric functions are the ones more widely used. This paper discusses a method for implementing se… more

Macro - Preprocessor for 6809 Cross Assembler

Description: It is frequently considered to be apparent two stages during assembly time. The first is the preprocessor stage in which a single instruction called the micro instruction is replaced with the sequence of instructions called the macro definition. The second is the processor stage in which the output from the first stage is assembled into machine language instructions for a particular computer. This paper descibes the first one which is macro-preprocessor stage.
