uses SOFTFP, so the Armel of hard mode is used as an ABI alone, called ARMHF. The uses hard mode to save 20 CPU cycles on average for each floating-point correlation function call. For an architecture that is important to each cycle of arm, this increase is undoubtedly huge. with no change in source code and configuration at all, on some applications, the use of ARMHF can get 20%--25% performance gains. For some programs that rely heavily on floati

Eabi (Embedded Application binary Interface), binary interface of embedded applications. AbiDefinition Abi describes the underlying interfaces between applications and the operating system, between applications and libraries, and between application components. Abi allows compiled target code to run in a system compatible with Abi without any changes. EabiSpecific Definition There is a QA like this on codesourcery: Https://support.codesourcery.com/G
