INSTRUCTION SET
S3C4530A
3-52
INSTRUCTION CYCLE TIMES
Coprocessor data operations take 1S + bI incremental cycles to execute, where b is the number of cycles spent
in the coprocessor busy-wait loop.
S and I are defined as sequential (S-cycle) and internal (I-cycle).
ASSEMBLER SYNTAX
CDP{cond} p#,<expression1>,cd,cn,cm{,<expression2>}
{
cond}
Two character condition mnemonic. See Table 3-2.
p#
The unique number of the required coprocessor
<expression1>
Evaluated to a constant and placed in the CP Opc field
cd, cn and cm
Evaluate to the valid coprocessor register numbers CRd, CRn and CRm
respectively
<expression2>
Where present is evaluated to a constant and placed in the CP field
Examples
CDP
p1,10,c1,c2,c3
; Request coproc 1 to do operation 10
; on CR2 and CR3, and put the result in CR1.
CDPEQ
p2,5,c1,c2,c3,2
; If Z flag is set request coproc 2 to do operation 5 (type 2)
; on CR2 and CR3, and put the result in CR1.
