\begin{tcolorbox}[title=Introduction]
	
This is a bunch of text for introductions that describes project, what it is about and that it compares RISC versus OISC architectures. Also motivation and academic papers.

		\item[$\bullet$] Efficient instruction space
		\item[$\bullet$] Generally easy to use but damn to low number of registers.
		\item[$\bullet$] Needs optimisation.

\begin{tcolorbox}[title=Results]
	Following functions have been implemented in assembly:

		\item[$\bullet$] Print ASCII, Binary, Hexadecimal and Decimal (8 and 16bit)
		\item[$\bullet$] 16bit multiplication
		\item[$\bullet$] 16bit division 
		\item[$\bullet$] 16bit modulus
		\item[$\bullet$] Sieve of Atkins (prime number calculator)
