What is the binary encoding of the following instructions?
a. STRB r1,[r2]
b. LDR r3,[r4,r5]!
c. LDR r3,[r4],r5
d. LDR r3,[r4,#-6]!
I have cheated and used the debugger’s disassembly feature to get
E5C21000
E7B43005
E6943005
E5343006
Consider STRB r1,[r2]. The encoding is 111 (always execute) 01 #PUBWL 001 (r1) 010 (r2) 000000000000
(zero offset)
# = 0 (use offset rather than shift)
P = 0 (preindex but don’t care)
U = 0 (up but don’t care)
W = 0 (word)
L = 1 (load)
The encoding is 1110100001001010000000000000 = E84A0000
