A Pthreads-Based MPI-1 Implementation for MMU-Less Machines

AzequiaMPI is a new thread-based full conformant implementation of the MPI-1 standard for MMU-less processors. It runs on a Linux desktop and on the entire Texas Instruments TMS320C6000 family of digital signal processors, as well as on MicroBlaze and PowerPC 405, which makes AzequiaMPI a useful tool in the reconfigurable MPSoC arena. AzequiaMPI needs a Pthreads box, what in most cases means the support of an underlying operating system as Xilkernel or uClinux. This paper discusses design issues and gives memory footprint and performance figures in a Xilkernel/PowerPC405 Xilinx FPGA.
