VLDR S0, [R5]
Load single-precision extension register S0. R5 is the ARM register with the base address for the transfer.
VLDR S2, [R5,#4]
Load single-precision extension register S2. R5 is the ARM register with the base address for the transfer; however we will be adding the numeric offset (#4) to the base address R5 to get the address used for the transfer.
