Rd: Destination ARM register. If Rd = 15, destination is ARM
N, C, Z, and V flags.
Compare 64-bit Integers
Description:
Compares two 64-bit integers and stores an integer representing the result in
the ARM920T register; the highest four bits of the integer result match the N,
Z, C, and V bits, respectively, in the ARM920T’s program status register, while
the bottom 28 bits are zeros. If Rd = 15, then the four status bits are stored in
the ARM status register, CPSR.
Mnemonic:
CFCMP64 Rd, CRn, CRm
Bit Definitions:
CRn: First source register
CRm: Second source register
Rd: Destination ARM register. If Rd = 15, destination is ARM
N, C, Z, and V flags.
3.5.7 Floating Point Arithmetic Instructions
Single Precision Floating Point Absolute Value
Description:
Computes the absolute value of a single precision floating point number:
CRd = |CRn|
Mnemonic:
CFABSS CRd, CRn
Bit Definitions:
CRd: Destination register
CRn: Source register
Double Precision Floating Point Absolute Value
Description:
Computes the absolute value of a double precision floating point number.
Mnemonic:
CFABSD CRd, CRn
