OpenSPARC, a series of open-source microprocessors based on the UltraSPARC T1 and UltraSPARC T2 multicore processor designs; Parallax P8X32A Propeller is a multicore microcontroller with an emphasis on general-purpose use; ZPU, a small, portable CPU core with a GCC toolchain. It is designed to be compiled targeting FPGA [4]
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.

OpenRISC is a project to develop a series of open-source hardware based central processing units (CPUs) on established reduced instruction set computer (RISC) principles. It includes an instruction set architecture (ISA) using an open-source license. It is the original flagship project of the OpenCores community.
The relevant term is of the porting target is computer architecture; it comprises the instruction set(s) and the microarchitecture(s) of the processor(s), at least of the CPU. The target also comprises the "system design" of the entire system, be it a supercomputer , a desktop computer or some SoC , e.g. in case some unique bus is being used.
In the absence of a widely accepted open source hardware license, the components produced by the OpenCores initiative use several different software licenses. The most common is the GNU LGPL , which states that any modifications to a component must be shared with the community, while one can still use it together with proprietary components.
Software compatibility can refer to the compatibility that a particular software has running on a particular CPU architecture such as Intel or PowerPC. [1] Software compatibility can also refer to ability for the software to run on a particular operating system. Very rarely is a compiled software compatible with multiple different CPU ...
