VaST Systems today (May 31, 2005) released its new Virtual Processor Model Transformer (VPM-T) for use by early adopters, enabling modification of the instruction set of a seed processor model.
Scheduled for general release next year, VPM-T, phase 1, is the newest addition to a line of virtual system prototyping tools that allow the creation of a virtual prototype system consisting of one or more Virtual Processor Models (VPM), a model of the communication internals and models of peripheral devices.
The skeleton of a virtual prototype is defined by the hierarchy of interconnection (bus) structures and the articulation points (bus bridges) between buses. Buses provide the communication and infrastructure support for the work and storage engines of the control system. The work engines are both processors and peripheral devices.
VaST founder and CTO, Graham Hellestrand said the new VPM-T allows VaST users to modify the instruction set of a VaST seed virtual processor model, which also describes the micro-architecture, pipelining and other behavior of a specific microprocessor.
With VPM-T, he said, users of the prototyping tools can generate a new VPM in the same microprocessor family by adding, removing or replacing instructions in the VaST seed VPM instruction set. "The behavior, timing and mnemonic aspects of an instruction can be changed independently," said Hellestrand.
VPM-T is the latest addition to a family of tools with "constructor" capability including platform constructor technology (PCT) within CoMET, which enables users to configure an entire virtual system prototype, and Peripheral Device Builder (PDB), which automates the creation of peripheral device models.
When available for general release, VPM-T pricing will start at $100,000 for a one-year, time-based, node-locked license.
