I am data-streaming from a netFT device using udp port. The data comes odered in chuncks of 36-bytes in a dubble array.
It is then converted to useful forcevalues using a swapbytes- typecast conversion between uint8 and int32. However this conversion is to slow for the live data stream and results in a slow buildup in the buffer. (which is solved with a dynamic buffer data collection). The swapbytes call is apprently the call that takes the longest time.
Is thera a way to do a faster/better conversion?
I can change the encoding for the data coming from the udp, but this changes the encoding to early in the conversion (the uint8 encoding rather than the int32 encoding?) and i dont know what changes in the conversion to do to accommodate the change? And would it even be faster?
If there is no alternative would it be faster to do the conversion in larger chuncks? It is now called with a for-loop with splitup data from a reading of aproxmatly 36000-bytes.
u = udpport('byte', 'IPV4');
data =[0 5 187 8 1 136 61 48 0 0 0 0 1 67 58 246 255 127 176 76 10 231 55 137 255 240 253 91 255 229 79 46 255 240 59 110];
fx = double(swapbytes(typecast(uint8(data(13:16)), 'int32')))/1000000;
