Draw the special purpose hardware organization for the following algorithm:

$//$ Encryption$/$Decryption with RC$6-$w$/$r$/$b

$//$

$//$ Input: Plaintext stored in four w$-$bit input registers A$,$ B$,$ C & D

$//$ r is the number of rounds

$//$ w$-$bit round keys S$[0,...,2$r $+3]$

$//$

$//$ Output: Ciphertext stored in A$,$ B$,$ C$,$ D

$//$

$//\text{'}\text{'}\text{'}$Encryption Procedure:$\text{'}\text{'}\text{'}$

B $=$ B $+$ S$[0]$

D $=$ D $+$ S$[1]$

for i $=1$ to r do

$\{$

t $=($B $*(2$B $+1))<<<$ lg w

u $=($D $*(2$D $+1))<<<$ lg w

A $=(($A $^$ t$)<<<$ u$)+$ S$[2$i$]$

C $=(($C $^$ u$)<<<$ t$)+$ S$[2$i $+1]$

$($A$,$ B$,$ C$,$ D$)=($B$,$ C$,$ D$,$ A$)$

$\}$

A $=$ A $+$ S$[2$r $+2]$

C $=$ C $+$ S$[2$r $+3]$ Note: can you please draw too, I will upvote
