This page provides detailed information about the Imperas Instruction Set Simulator for the POWER powerpc32 (mpc82x) processor core.
This page is information about the powerpc32 alias of the mpc82x variant.
Processor IP owner is IBM. More information is available from them here.
The Imperas Instruction Set Simulator (ISS) is a product of Imperas Software Ltd. It is a binary licensed by Imperas as a commercial product. It is also available in OVP packages for evaluation and demonstration.
The Imperas ISS uses the OVP Fast Processor Models and dynamically loads them as selected.The OVP Fast Processor Models are written using the OVP VMI API that provides a Virtual Machine Interface that defines the behavior of the processor.The VMI API makes a clear line between model and simulator allowing very good optimization and world class high speed performance.
The processor models are provided as a binary shared object and are also available as source (different models have different licensing conditions). This allows the download and use of the model binary or the use of the source to explore and modify the model.
The models have been run through an extensive QA and regression testing process.
If you develop your own processor models using the OVP VMI APIs then they can be used with the Imperas ISS.
Traditionally, processor models and simulators make use of one thread on the host PC. Imperas have developed a technology, called QuantumLeap, that makes use of the many host cores found in modern PC/workstations to achieve industry leading simulation performance. To find out about the Imperas parallel simulation lookup Imperas QuantumLeap. There are videos of QuantumLeap on ARM here, and MIPS here. For press information related to QuantumLeap for ARM click here or for MIPS click here. Many of the OVP Fast Processor Models have been qualified to work with QuantumLeap - this is indicated for this model below.
This ISS executes instructions of the target architecture and provides an interface for debug access. An interface to GDB is provided and this allows the connection of many industry standard debuggers that use the GDB/RSP interface. For more information watch the OVP video here.
The ISS also works with the Imperas Multicore Debugger and advanced Verification, Analysis and Profiling tools.
The ISS is downloadable (needs registration and to be logged in) in package Demo_Processors for Windows32 and for Linux32. Note that the ISS is also available for 64 bit hosts as part of the commercial products from Imperas.
This ISS uses the CPU with Model Variant name: powerpc32 (mpc82x)
PPC32 Family Processor Model.
Open Source Apache 2.0
This model is currently under development. The FPU is incomplete.
Basic verification of ISA against reference has been performed.
The CPU model being used is downloadable (needs registration and to be logged in) in package powerpc32.model for Windows32 and for Linux32. Note that the CPU model is also available for 64 bit hosts as part of the commercial products from Imperas.
OVP simulator downloadable (needs registration and to be logged in) in package OVPsim for Windows32 and for Linux32. Note that the OVP simulator is also available for 64 bit hosts as part of the commercial products from Imperas.
