Hi all: I'm successfully run OPUS in cortexM4 arm architectures using a cross compiler gcc-arm-none-eabi . I recommend to uses the following precompile flags before to compile you code: arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -mfloat-abi=hard -mfpu=fpv4-sp-dl16 -std=c99 -fasm -DARM_MATH_CM4 -DOPUS_ARM_INLINE_ASM -DOPUS_ARM_ASM .... and in your configuration file of OPUS you could use the following configuration : #define VAR_ARRAYS #define FIXED_POINT /*Actually I'm working in a fixed point but I also test it with float point and also works for me*/ #define OPUS_BUILD. Test an...
