This is an article related to what is commonly called the Virtual Platform or Virtual Prototype. There are probably many definitions of what this means. Here it means the Virtual Platform as a software model of a hardware system, created for the purpose of running embedded software and verifying the hardware/software interaction. Here are some general characteristics to help clarify what the Virtual Platform is: • Runs unmodified target code • Uses instruction accurate models of processors • Provides a full programmers view • Runs very fast (may be faster than the hardware it emulates) • Has excellent visibility and control (compared to physical hardware) • Is easy to distribute to many users Virtual Platforms have been available since somebody had the idea to make a software model of the hardware. I expect that many software engineers already understand the details about how to select operating systems, write device drivers, create and populate file systems, cross compile software, program flash memory, etc., but sometimes software engineers are not familiar with virtual systems since somebody else sets up all the infrastructure and they just “add code” in the right place. I’m sure that virtual platforms are (or will become) critical to verification engineers and people who have worked primarily with RTL simulation in the past and are making the transition to the next level of abstraction.
Virtual Platforms can play a key role in system verification and delivery of high quality software sooner in the process. The hardware system to be virtualized is the. It is an older board that was supplied by ARM and according to the is no longer promoted because newer hardware platforms have been developed. Not being a state of the art board that means there is a lot of public information available as well as software.
One of the benefits of the Virtual Platform becomes apparent immediately. First, a software company probably wouldn’t understand the need to buy a board to develop embedded software. Next, if a physical board was needed I doubt any readers would buy the board to learn about how embedded software development and verification works. Since we have Virtual Platform technology nobody needs to buy any hardware and everybody can contribute. All that is needed is a computer, and the Qemu emulator. Instead of actually reading the User Guide, we can start with a quick overview of the Integrator board and its memory map: ARM926EJ-S CPU Peripherals Base Address Primary Interrupt Controller 0x14000000 Secondary Interrupt Controller 0xca000000 Counter / Timer 0x13000000 Real time Clock 0x15000000 UART 0 0x16000000 UART 1 0x17000000 Control Registers 0xcb000000 Keyboard Controller 0x18000000 Mouse Controller 0x19000000 Multimedia Card 0x1c000000 Ethernet Controller 0xc8000000 LCD Controller 0xc0000000 There are many uses for the Virtual Platform.
A common one we can start with is to boot the operating system and run applications. Lord of the rings the complete recordings rar. Another one is to write device drivers and debug them. Linux will be used as the operating system to load on the virtual device. Again, there is a wealth of information available and Linux is becoming popular as an embedded operating system. To start, download QEMU which will emulate the Integrator board and boot Linux.
QEMU is an open source processor emulator which is available to run on both Linux and MS Windows. If you have a Linux machine it may be installed already or can be installed using your package manager. Once you have qemu installed it’s time to get a Linux kernel and file system and boot it. There are Fedora and Debian howto links on the page with step by step guides. An easy starting point.
