Sound improvements

A project log for Lion FPGA CPU/Computer

A 16-bit FPGA CPU I call Lion CPU and a computer, the Lion computer. Everything built from scratch.

In order to have better sound effects to add in the future to Galaxians clone or other games, I made some additions.

In every channel I added the option to add a second frequency related to the playing one. This frequency can be up to an octave higher. It is controlled with a 4 bit parameter n.

An other change is that the noise generator is clocked by the frequency of a channel when noise is enabled in that channel and its output is less harsh.
