ERTOS L4 site.
For general information on L4 refer to L4HQ.
The L4 microkernel was developed and implemented on ix86 platforms
by Jochen Liedtke, then at GMD, Germany. Liedtke continued development
of the Intel version of L4 while at IBM TJ Watson
Research Center and later at the University of Karlsruhe.
We have developed L4 implementations for several platforms:
The above kernels are obsolete now that the portable Pistachio kernel has been released. We have
contributed the MIPS and Alpha ports of that kernel. We have also done a
port to the StrongARM architecture, which will be released soon. We are
also working on a version for the 64-bit IBM Power architecture and may
commence a SPARC port later this year.
L4/MIPS: a stable version for
the MIPS R4x00 processor, to our knowledge the world's fastest
kernel for that architecture.
L4/Alpha: a stable version
for Alpha multiprocessors, which was based on a rudimentary kernel
developed at the Technical University of Dresden. This is the first
released SMP version of L4.
