Now PCB are finished, I work on the FPGA. RAM_controller and RAM_switch blocks are designed and tested. For the good inputs, there are the good outputs in simulation.
Today, I thought about the problem of calculation: even if the calculations can be done before and then stocked in RAM, I thought that it can be faster to do that on the FPGA. It is the case but, the difference is not quite important and, writing a C program to do it is really easier and faster. S, I wrote this program which create a text files containing the result of pre-calculations. This program is working.
I designed the block which will communicate with the gumstix but, I have some doubts on it and, I didn’t test it.
Now, I have to design the other parts of the FPGA and, to adapt the JRunner program (it is the software we will use to program the FPGA thanks to the gumstix) which was design for a windows system.
