PRASYNTH DEMO no midi
So, I managed to put together an incredibly primitive synthesizer )) Now it works as a doorbell it plays 4 notes in a cycle. The composition of the FPGA logic: 1) Generative logicoscillator from a counteraccumulator with the output of the highorder bit as sound 2) Virtual user processor NIOS2, which feeds the required numberdelta to the control input of the oscillator to create a cyclic count with the desired tone frequency, as well as changes this number to create a repeating melody 3) External SDRAM 128 Mbit for storing the control program and the processor s operation The oscillator is able to reproduce any wave from the table, but creating a table is a separate task, until it was postponed for the future, as a result, only a onebit wave plays in the test. As a summary, I want to immediately warn those who want to repeat this creating your own processor and independently connecting and programming SDRAM is not an easy task, just knowing the little bit and noobcoding is not enough, you ha
