MutekA

General presentation

MutekA is a kernel-mode lightweight operating system for Multiprocessor System on a Chip. It is build from scratch targeting the POSIX thread API.

MutekA is build on top of an Hardware Abstraction Layer that limits the porting effort. It currently targets the following architectures:

• ARM7 (​http://www.ens-lyon.fr/LIP/Pub/Rapports/RR/RR2006/RR2006-12.pdf)
• Micro-Blaze, tested on a Spartan3 platform (3 processors, Motion-JPEG application)
• Sparc V8, MPSoC architecture build with !SoCLib

and comes in two flavors:

• SMP (Symmetric multiprocessing), in which the threads share the processor pool in a fair manner, first come first served.
• DS (Distributed Scheduling), in which a task is assigned to a processor at creation time.

The libraries currently available are :

• Native POSIX Threads (libpthread)
• Standard C library (libc)
• Process Network Communication (libcomm)

The MutekA kernel is currently being restructured :

• code clean up
• peripheral accesses through drivers
• modularity
