Information for BareMetalMips32Single
This page provides detailed information about the mips.ovpworld.org BareMetalMips32Single Virtual Platform / Virtual Prototype.
Description
Bare Metal Platform for an MIPS32 Processor (variant 4Km).
The bare metal platform instantiates a single MIPS32 processor instance.
The processor operate using big endian data ordering.
It creates contiguous memory from 0x00000000 to 0xFFFFFFFF.
The platform can be passed any application compiled to an MIPS32 elf format.
./platform.exe -program application.CROSS.elf
If this platform is not part of your installation, then it is available for download from www.OVPworld.org.
Licensing
Open Source Apache 2.0
Limitations
BareMetal platform for execution of MIPS MIPS32 binary files compiled with MIPS SDE CrossCompiler toolchain.
Location
The BareMetalMips32Single virtual platform is located in an Imperas/OVP installation at the VLNV: mips.ovpworld.org / platform / BareMetalMips32Single / 1.0.
