It was implemented in an iterated bit-serial fashion in a bid to keep the hardware usage low, though it turned out to be more complex than ...
Previous blogs: FPGA: Making Waves FPGA: Waves 2: Simple Sinewave FPGA: Waves 3: Computed Sinewave Oscillators FPGA: Waves: 4 Tinker, Taylor, Soldier, Sine FPGA: Waves: 5 CORDIC Sine FPGA: Waves 6: Reconstruction Filter   Introduction   I have a small Brevia 2 development board from Lattice Semiconductor featuring one of their XP2-family FPGAs. I'm using it to explore, in a very simple, basic kind of way, digital signal generation and processing. These blogs aren't tutorial ...
Previous blogs:   FPGA: Making Waves FPGA: Waves 2: Simple Sinewave FPGA: Waves 3: Computed Sinewave Oscillators FPGA: Waves: 4 Tinker, Taylor, Soldier, Sine FPGA: Waves: 5 CORDIC Sine   Introduction   In the last blog, I looked at computing a sinewave using a CORDIC method. It was implemented in a iterated bit-serial fashion to keep the hardware usage low, though it turned out to be more complex than I had anticipated because of some of the fiddly control necessary.   ...
