Original on-chip bus for combining hundreds of processing cores has been developed


 

The development of simple packet bus (SPBUS), enabling to ensure connectivity of hundreds of different devices inside a chip, is finished. SPBUS implementation is written entirely on VHDL without using closed source licensed IP. The developed bus is exceptionally compact in terms of FPGA or VLSI hardware resources usage, along with that it provides delays less than 50 cycles during data transfer.

The first PHP script on Minix written without using x86 platform!


 

PHP support has been added to the developed platform. For now, OS Minix3 OS is officially supported on x86-compatible processors only. Different versions of this OS could be found but they're rather experimental. For that reason, without false modesty, we claim, that this is the first PHP script on Minix written without using x86 platform.

General-purpose RISC core has been chosen


 

For prototyping multicore processors on FPGA we’ve been looking for a core, satisfying such requirements as open flexible architecture, GCC compatibility, minimum size on FPGA, 32-bit RISC architecture, perfect 'layout' on Xilinx FPGAs, performance at least 1 DMIPS/MHz.
