INSTRUCTION SET
S3C4510B
INSTRUCTION CYCLE TIMES
All instructions in this format have an equivalent ARM instruction as shown in Table 3-11. The instruction cycle
times for the THUMB instruction are identical to that of the equivalent ARM instruction.
Examples
EOR
ROR
NEG
CMP
MUL
R3, R4
R1, R0
R5, R3
R2, R6
R0, R7
; R3 : = R3 EOR R4 and set condition codes
; Rotate right R1 by the value in R0, store
; the result in R1 and set condition codes
; Subtract the contents of R3 from zero,
; store the result in R5. Set condition codes ie R5 = - R3
; Set the condition codes on the result of R2 - R6
; R0 : = R7 * R0 and set condition codes
