The Cortex-A5 FPU implements the ARMv7 VFP extension.

Software can identify this extension and the features it provides, using the feature identification registers. This extension is in the coprocessor space for coprocessors CP10 and CP11. You can access the registers using the VMRS and VMSR instructions, for example:

VMRS <Rd>, FPSID ; Read Floating-Point System ID Register

VMRS <Rd>, MVFR1 ; Read Media and VFP Feature Register 1

VMSR FPSCR, <Rt> ; Write Floating-Point System Control Register

See VFP register access for a description of the registers.

In addition there are coprocessor access control registers. See VFP register access.
