How to generate .rbf files in Altera Quartus?

问题 What are .rbf files and how can i generate them from the Quartus output file .sof on windows ? 回答1: With Quartus II GUI go to File => Convert Programming Files, where .rbf can then be selected as output file, and the .sof can be given as input file. The conversion setup can be saved from the GUI for use in a command line like > quartus_cpf -c convert_sof_to_rbf.cof 回答2: An RBF is a " Raw Binary File ". It represents the raw data that will, for example, be loaded into a flash memory for

arctan function with cordic with vhdl

问题 I want to design arctan function with VHDL for using in demodulator design. I need a division & arctan function block. I have two signals, assumed that sin(alpha) and cos(alpha) from previos blocks. I want to retrieve alpha with using division [sin(alpha)/cos(alpha) = tan(alpha)] and then arctan function. I found that it is possible to do that with cordic algortihm, but a bit confused. Do you have any recommendation, docs or sth. how to design division & arctan with cordic in vhdl? Thanks in

问题 I'm writing a userspace driver for accessing FPGA registers in Python 3.5 that mmap s the FPGA's PCI address space, obtains a memoryview to provide direct access to the memory-mapped register space, and then uses struct.pack_into("<I", ...) to write a 32-bit value into the selected 32-bit aligned address. def write_u32(address, data): assert address % 4 == 0, "Address must be 32-bit aligned" path = path.lib.Path("/dev/uio0") file_size = path.stat().st_size with path.open(mode='w+b') as f: mv
