Information for BareMetalOr1kSingle
This page provides detailed information about the ovpworld.org BareMetalOr1kSingle Virtual Platform / Virtual Prototype. Table 1: Components in platform
Description
Bare Metal Platform for an OR1K Processor.
The bare metal platform instantiates a single OR1K 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 OR1K elf format.
./platform.
Licensing
Open Source Apache 2.0
Limitations
BareMetal platform for execution of OR1K binary files compiled with OR1K CrossCompiler toolchain.
Location
The BareMetalOr1kSingle virtual platform is located in an Imperas/OVP installation at the VLNV: ovpworld.org / platform / BareMetalOr1kSingle / 1.0.
