A0B36APO Virtual Hardware
Students have to work with specialized hardware. This page describes how to use the virtual implementation of the specialized hardware -- this can help students to work at home without the access to the real hardware.
Qemu is a processor emulator which enables to run separate Operating System on Virtual Hardware.
APOHW comprises PCIe I/O card and Simple terminal (keyboard + text LCD).
How to obtain the source code:
git clone git://github.com/CTU-IIG/qemu.git -b apohw
How to compile it:
./configure --enable-system --target-list=i386-softmmu --enable-sdl --enable-kvm
To compile Qemu on bare Ubuntu 12.04, you will need to install zlib1g-dev, libglib2.0-dev, libsdl1.2-dev
How to run it:
./i386-softmmu/qemu-system-i386 -device apohw \ -hda ../../debian_lenny_i386_standard.qcow2 \ --boot c \ -enable-kvm
You need to have some image file with GNU/Linux installed on it. KVM command is optional.
In another terminal then run:
telnet localhost 55555
... and perceive the miracle
What is not implemented
- Proper timing features of the hardware
- I/O card is PCI, not PCIe -- however memory access is the same.
- HD44780 does not support 4bit access
- HD44780 does not support display shifting
- HD44780 does not support editable CGRAM
