Work continues on the discrete YASEP, with frequent log posts on hackaday.io.

In one post, the SHL group's instructions have been reordered :

• 0 : SHR
• 1 : SHRO
• 2 : ROR
• 3 : SAR
• 4 : SHL
• 5 : SHLO
• 6 : ROL
• 7 : BSWAP

Then the structure of the SHL unit has been refined and a detailed diagram is drawn:

There is still some room for extra features and the I/E unit (Insert/Extract) might benefit from the unused inputs of the last MUX4 layer :-)

By 2015 my development process shifted to the HaD.io platform and more tinkering occured here. A bit later, critical YASEP development files were lost in a HDD crash and I didn't have the force to rescue and resume the project.

This series of logs keep essential traces of design decisions that will help to reboot the project.
