Floating Point

An Assembly Language Project

For the final project of Microcontrollers and Embedded Systems, we created a program that approximated the process of interpreting  data transmitted from a router to a phone. Largely, the project was more aimed towards gaining further understanding  of ARM-7 and floating point arithmetic than the actual simulation of data transfer.

First, the initial signal was modulated by a given higher frequency signal. A routine for floating point multiplication was created to allow for this process. Then, the signal was multiplied again by a given carrier signal. A low pass filter was applied to the signal by convolving the signal with a given filter data set. The outputted signal was then translated to ASCII characters.
