Compute Complex Roots - Assembly x87+x86

" In this assignment, you shall write a program in x86 assembly language, to find a single root of a polynomial of complex coefficients. This assignment shall require you to work with the x87 subsystem, the SSE register set, arrays, and interfacing with the C standard library. The x87 does not support complex numbers , so you will need to implement the representation for complex numbers and the functions defined over them using support for floating-point numbers in the x87 subsystem.

Arbitrary Precision Calculator for Big Numbers - Assembly x86 + C

" In this assignment you shall write a postfix-based calculator for integer arith- metic, somewhat similar to the dc program on Unix/Linux (read over the man page for dc). The program will be written in a combination of C and x86/64-bit assembly language. This version works with arbitrary-precision integers, providing functionality similar to that of bignums in Scheme, int in Python, or LargeInteger in Java. Your calculator will implement the following functionality: • Addition • Subtraction • Multiplication • Division "

Virtual machine for SIC - Assembly x86

" The SIC computer architecture has only one instruction: SBN A, B, C . SBN stands for Subtract & Branch if Negative . This is an example of a one- instruction computer , of which many are known. SIC is not a realistic com- puter architecture, in the sense that it would be worth implementing it in hardware, but a theoretical one, in the sense that it is Turing-complete. For this assignment, you will write the following tools:

1. A virtual machine for SIC, emulating the SBN instruction. This shall be written in x86 assembly language.
2. A second virtual machine for SIC, emulating the SBN instruction. This shall be written in SIC assembly language, shall only use the instruction SBN , and shall run on top of the virtual machine that you wrote in x86 assembly language. This program is essentially a bunch of numbers that we too could run on our own virtual machine for SIC. You are given the code for computing Fibonacci numbers. The finish-line for this assignment is to be able to run "a tower" consisting of Fibonacci running on top of (2) running on top of (2) running on top of (2), and so on, as many times as you like, running on top of (1). The ability to run such a "tower" of virtual machines will be our demonstration that your implementation of the virtual machine is correct."
