A network server for emulating CPUs (DCPU 1.7 specifically), and providing API and protocols to support associated hardware emulation, provisioning and management.
- CPUs and hardware store components of state in isiCPU.
- Fairly abstract and portable hardware and CPU interface for emulation.
- Network access to multiple DCPU terminals (Keyboard and Display).
- Multiple DCPUs can be run at once, and can be added at runtime.
- Configurable TCP port.
- supports both IPv4 and IPv6 using TCP sockets.
- DCPU disassembly and debugger.
- Endian swap option for bin files.
- bin files load to a "rom" device.
- Data persistence via external Redis database.
- load estimation and support for multiple CPUs (mostly works)
- single-threaded processes, multiple processes must be run on a server to use more cores.
- DCPU 1.7 Emulation
- DCPU generic ASCII Keyboard
- DCPU generic Clock
- Mackapar 3.5" floppy
- generic FlashROM/EEPROM
- Nya Elektriska LEM 1802
- MEI Imva
- MEI EDC (direct connect)
- 2 channel speaker
- Kai Communications Hardware Interface Card (HIC)
- Add various new hardware devices
- Provide a network interface to the CPU and associated hardware. (WIP)
- Runtime debug of hardware and CPUs from network API. (WIP)
- Emulation layer will provide an API that allows add-on shared libraries.
- Add-on libraries will be able to be loaded during emulation.
- Add CPU TR3200
- Add CPU DCPU-16N
- Add CPU Mira2204
- support clustered networking.
- Multiple processes on the same server will use Unix Domain sockets (or equivilent).
- support using UDP sockets.
- each instance in a cluster should allow migrating emulation state(s) to another server, both for redundancy and load sharing.
- instances will be able to be added and removed dyamically from a cluster.
- isiCPU is written in C++ using the c++11 standard or newer.
- The CPU and Hardware API must be in C++.
- Dynamic libraries should provide a C-style entry point (extern "C")
- JIT (if used) may include assembly language, which should support IA32 and amd64.
- (planned) optional GPU acceleration features?
isiCPU was designed for GNU/Linux or compatible BSD systems. The current build method is simple.
make
isiCPU includes a built-in debugger that is enabled with -D on the command line.
Some of these features work with debugging disabled.
- x : exit
- enter : run 1 instruction
- c : continue execution
- bHHHH : toggle break point at HHHH (must be 4 hex char address)
- rHHHH : read memory at HHHH (must be 4 hex char address)
- fnum : run for decimal num of cycles
- t : toggle trace on execute
