$2.$ a$)$ Demonstrate the basic design rules in RISC philosophy. $(2$M$)$

b$)$ Identify and summarize the values of R$0$ and R$1$ register after the following instruction is

executed. $(3$M$).$

R$0=0$x$00000000,$ R$1=0$x$08000003,$

MOVS R$0,$ R$1,$ LSL #$2$

c$)$ Develop an assembly language program for the following. A number $0$x$00000002$ is stored

in $$R$7$ register. $(5$M$)$

$$ If the number is having even number of $1$s$,$ Move the lower half$-$word multiplied by $8$

into $$R$3$ register.

$$ If the number is having four continuous $0$s$,$ move upper half$-$word divided by $8$ to

$$R$1$ upper half$-$word.
