Hello all, I am working with GNU Radio on a Zedboard (which is a Xilinx Zynq-7000 based device). The linux dist. used is the one from this page: http://gnuradio.org/data/sdk/zedboard_armv7a-sf-vfp-neon/
I have described some functions on the FPGA of the Zynq and I am able to send and receive data from a gnuradio .py , and everthing seems to be working ok. I would like to measure how the use of the FPGA impacts the CPU performance, I am thinking on measuring the % of CPU usage of a GNU Radio block that performs all the calculations only in the ARM processor and the same function but co-processing some data in the FPGA. The problems that I have in doing that measure is that the Linux dist. used has no graphical interface and only one command line, so, I am not able to run the .py file on one termianl and other programm on other terminal like TOP for CPU usage measurement. I tried with a bash script but when I execute the .py file it "blocks" everthing. I have to manually press enter or stop the process, depending on run option I chose initially in the flow graph options, "Generate Options: No GUI" and "Run Options: Prompt to exit" or "Run to completion". Any ideas on how to handle this?. Thanks in advance. -- View this message in context: http://gnuradio.4.n7.nabble.com/Estimate-CPU-usage-tp56794.html Sent from the GnuRadio mailing list archive at Nabble.com. _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
