| In the makefile, I modified some of them so that you could just change the value of VH to support virtual hosting. The key ideas are 1) Add -mvh to LDFLAGS 2) Comment/Remove the code for do_printf.c annd printf.c --------------------------- In the makefile, at around line 8, add # VH --> virtual hos... |

| 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... |

If your applications need the DSP ISA Extension support , please use linking options “ -ldsp -mext-dsp -mext-zol ” instead to obtain better performance. For certain Andes DSP libra... |
