1. Open a toolchain console. 2. Use dd if=/dev/urandom of=blob.bin bs=1 count=16 to generate a blob.bin file. You can use hexdump -C blob.bin to check the content. 3. Use nds32 le-mcu lib-objcopy to transform it to an object file. nds32 le-mcu lib-objcopy -I binary -O elf32-nds32 le -B n1h blob.bin ...

q值是介於-1和1之間,小於1,[-1, 1),當使用時,雖說q15當於int16,一般不建議直接給值,因為它相對的值可能會很小,當使用者把這些值放入dsp的運算function中時,常常得到結果為0。所以應以轉換的方式給值,如 q15value = convert_float_to_q15(0.123); 由上式可知q15value的值是0.123 在demo-dsp.tgz中有轉換公式 static inline q15_t convert_float_to_q15(float x) { q31_t q31; q15_t q15; x *= 32768.0f; x += (x < 0.0f...

The default standards of gcc is gnu89 and g++ is gnu++98 . To check the default values in the command line, please use the following corresponding commands. gcc: nds32le-elf-gcc -E -dM - < /dev/null | grep __STDC_VERSION__ The absent of output represents gnu89. If the output is “#define __STDC_VERSI...
