Calculate Maximum with DSP builder

Hi, I have to calculate the delay between 2 signals so I've done a crosscorrelation. After that I have to calculate the index of the maximum for each window, I've done it in Simulink and I'm ...

i attached what i came up with. i looked for the maximum of an 8-bit random signal. my "packet size" was 100 samples. the top plot is the random data, the bottom is the maximum value held in the delay. as you can see the maximum is held until the packet is done in which case the maximum is cleared to 0. now that i look at my results the input was signed and i was only looking for maximum (not absolute value) but you get the picture. ;)
