MDcore is an Open-Source library implementing the core functionality of a Molecular Dynamics engine. The engine is inherently multi-threaded and runs efficiently on multi-processor/multi-core shared-memory architectures.
lilpM32 is a MIPS-like processor designed in Logisim, assembler program and documentation for them.
Complete assembler and fully functional instruction set with I/O and subroutines features allow to write full-blown complicated programs.
DSPemu emule a digital signal processor TMS320F243, with console interface showing the registers and memory. With DSPemu is possible test algorithms such as Filter, FFT/IFFT. This can be integrate and used with a circuit simulator.
