I bought a ADSP-BF533-EZkit-LITE V2.1 to develop a speech codec application using SPEEX. I have tested SpeexEcho project from both BlackfinSDK-Rel201 and BlackfinSDK-Rel310. When disabling SPEEX processing, i.e. using PASS-THROUGH mode, the output voice is ok, which is exactly as the input voice. However, when enabling SPEE...

...performance changes when you are switching from floating point to > fixed point with using gcc? And to Blackfin asm? float->fixed : at least 10x faster (but probably more like 100x) fixed->asm: Almost 2x faster with gcc, but probably less difference with VDSP. > When I am using BF537 Ezkit Lite(600MHz) - I am compressing sound with speex > (8 KHz, 16 bit, one channel). > To compress 1 second of sound it takes: > 1)floating point - 8 seconds > 2)fixed point - about 4 seconds. Definitely not normal. Using quality 8 (15 kbps) at 8 kHz and complexity 2 (default) takes about...
