PLEASE ADD RELEVANT INFORMATION ABOUT THE FLAGS MENTIONED BELOW:

THESE ARE FLAGS FROM LINUX SYSTEMS...

Half: half-word loads and stores

Thumb: a 16-bit instruction set with its own state to improve compiled code-density

Fastmult: 32x32 -> 64-bit multiplication

Vfp: stands for vector floating point and is an fp unit coprocessor extension to the ARM architecture that provides low-cost double and single precision fp computation (DONE) ARM architecture - Wikipedia

Edsp: DSP extensions

Neon: The Advanced SIMD extension (aka Neon or "MPE" Media Processing Engine) is a combined 64- and 128-bit SIMD instruction set that provides standardised acceleration for media and signal processing applications.

Vfpv3: VFP version 3. VFPv3 has 32 64-bit FPU registers as standard, adds VCVT instructions to convert between scalar, float and double, adds immediate mode to VMOV such that constants can be loaded into FPU registers

Tls: TLS register

Vfpv4: VFP version 4 with fast context switching. VFPv4 has 32 64-bit FPU registers as standard, adds both half-precision support as a storage format and fused multiply-accumulate instructions to the features of VFPv3.

Idiva: SDIV and UDIV hardware division in ARM mode

Idivt: SDIV and UDIV hardware division in Thumb mode

Vfpd32: VFP with 32 D-registers

Lpae: large physical address extension (>4GB phys mem on 32-bit arch)

Evtstrm: kernel event stream using generic architected timer

Crc32: hardware-accelerated CRC-32
