   What is a vfp11 coprocessor?

   • The VFP11 coprocessor implements all the instructions and modes of the VFPv2 architecture. The VFPv2 architecture adds the following features and enhancements to the VFPv1 architecture: The ARM v5TE instruction set. This includes the MRRC and MCRR instructions to transfer 64-bit data between the ARM1136JF-S processor and the VFP11 coprocessor.

   What does vfp11 do?

   • The VFP11 coprocessor bounces an instruction when it fails to signal the acceptance of a valid VFP instruction to the ARM11 processor. This action initiates Undefined Instruction processing by the ARM11 processor. The VFP support code is called to complete the instruction that was found to be exceptional or unsupported by the VFP11 coprocessor.

   What is a vfp11 register file?

   • The VFP11 register file stores single-precision, double-precision, and integer data in the same registers. For example, D6 occupies the same registers as S12 and S13. The usable format of the register or registers depends on the last load or arithmetic instruction that wrote to the register or registers.

   Load data is written to the VFP11 coprocessor on a dedicated 64-bit load data bus between the ARM1136 processor and all coprocessors. Data is received by the VFP11 coprocessor in the Writeback stage. Data is written to the register file in the Writeback stage, and available for forwarding to data processing operations in the same cycle.

VFPv3 is implemented on ARM architecture v7 and later (e.g. Cortex-A8). Some VFPv3 variants are:

   This paper presents the detailed design of the ARM VFP11 divide and square root synthesisable macrocell. The macrocell was designed using the minimum-redundancy radix-4 SRT digit recurrence algorithm, and this paper describes a novel acceleration technique employed to achieve the required processor clock frequency of up to 750 MHz in 90 nm CMOS. Logical effort theory is used to provide a delay ...
