Simulated Devices

The Java System Simulator does not simulate a single, hardcoded, computer architecutre. Instead it simulates individual devices which can be connected using a simulation configuration file. In this way, different architectures with different parameters can be configured and simulated. Each simulated device has a number of parameters which can be set in the simulation json configuration.

The following classes of devices are currently available:

Memory - Different types of memory are simulated, including ROM/RAM, with different word sizes 4-bit, 8-bit, 16-bit.
CPU - The Central Processing Unit executes programs for a specific architecture.
BUS - Devices are connected via BUSes (which can be Data BUS and/or Control BUS).
Special ICs - Special integrated circuits (ICs), such as Programmable Interrupt Controller (PIC), Programmable Peripheral Interface (PPI), Direct Memory Access (DMA) controller.
Terminals - In certain computer architectures, display is accomplished via terminals connected on the serial interface
Disk controllers - Access to floppy disks or hard disks is accomplished via disk controllers
