Log#34 : The YASEP and Defora

A project log for YASEP News archives

A backup of the blog before the host erases it. A good opportunity to review the development, twists and turns of this ISA !

Today I think that one big issue with the YASEP project has been solved.

I met Pierre this week, and I start to discover the awesomeness of his Defora project. "Debian For All" turned into creating a whole new, compact, totally GPLv3 system. With almost no dependency from existing systems, yet compatible with them... Perfect for embedded computing too !

We just started to work on a C version of the existing JS assembler and we consider writing a C99-compliant compiler.

YES, you have read it : the YASEP will have binaries generated from C code ! And good code, at that, since it does not go through GCC !

Many roadblocks are now removed. When the code generation tools are in place, we can then simulate/emulate the core and start to write a microkernel...

What this means for me is that I can finally stop worrying about the operating system and application layer. The YASEP will not use Linux and I won't be forced to use the huge GCC armada. I will also have more time to focus on the hardware architecture and implementation. And Pierre is a security specialist...

Oh, by the way : YGWM won the 2nd rank (ex aequo with Pierre's Defora) at the "Open World Forum Code Contest" this week. A new, shiny, professional laptop was given away by HP and will become my main workstation. Going from an Atom to a Core i5 makes me feel spoiled :-)

Defora is still in development and has grown a lot, while the YASEP morphed into... stuff...

The HP2540 laptop has lived a great life before suffering a breach. Right now I'm using his sibling, a 2560p that also is used intensely.

Open World Forum turned into a corporate even with time, losing all the hackers' crowd...

These days, code generation from C is not really a concern as I dive down deep into hardware considerations.
