[Discuss-gnuradio] USRP2 FPGA USAGE

2008-09-22 Thread Uwe Bonnes
Dear Matt or anybody else using USRP2, can anybody give us the usage pattern of the USRP2 FPGA, e.g. what is needed by the AEMB, by the Ethernet MAC, for signal processing and any other part eating up a substantial part of the resources? To get the number, Webpack isn't enough... Thanks -- Uwe
