Free emulator paradise software for linux

cereal is an emulation framework designed to allow easy emulation of interconnected modules. Its main component is an 8051 emulator module, so it can be used as an 8051 emulator.

The reason for writing cereal was an 8051 embedded controller which should control an engine using pulse-width modulation, read the resulting flow from a flowmeter, and regulate the output to keep flow at a given value.

In the real world, it takes about two seconds for the algorithm to stabilize, and emulating two seconds using conventional emulators (computing the engine input, the real flow, the feedback frequency) by hand is simply impossible to do.

Using cereal, it took about two hours to create a module emulating the engine/flowmeter combination, along with a window showing the current values. Then it is trivial to connect this module to the 8051 module and just sit back and watch the result.

Another, more trivial example is a multiplexed display/keyboard combination (in my case, selecting one of four 8-segment LCD displays). Instead of watching the port bits, why not create a module that shows the output graphically as four displays?

In addition to these possibilities, cereal offers breakpoints, watches, evaluate/modify dialog (which can solve 2 * x + 1 = 5). The KDE GUI also can be extended using KParts (8051 interface is provided as a KParts plugin).

Also included is a command interface usable for creating testsuites for your programs (or for cereal itself - cereal has over 400 tests in its testsuite), and a simple 8051 disassembler.

Wide Area Link Emulator enables you to set and test various parameters of a WAN access link (also known as a bottleneck link) before testing on a fully-functional network.

Any ISP has a high bandwidth LAN (of the order of tens of Mbps, e.g. Ethernet) and a WAN access link with relatively low speeds (of the order of a few Kbps to a few Mbps). To be able to evaluate the ISPs performance, actual tests will have to be conducted on a live, fully functional network. This would imply enabling certain features in communication equipment which could be detrimental to the proper functioning of a commissioned network. To address such a problem of being able to characterize/quantify the network operation in terms of its performance with respect to various parameters, a test-bed emulating the ISPs connectivity to the Internet would be an ideal solution.

An important factor in setting up such a test-bed, is emulating the WAN Access Link. Using complex hardware is costly. Such a link can however be easily implemented by emulating the scenario on popular physical technology such as Ethernet. By changing the TCP/IP stack on a Personal Computer, the rate at which packets are injected into the network can be controlled and other necessary features can easily be added.

WALE was implemented in 2 phases and the first version can emulated bandwidths up to 8Mbps and uses FIFO queues with drop-tail.

WALE v2 can emulate bandwidths of up to 80Mbps(a 10-fold improvement over version 1) due to the stripped down version of Micro-second resolution timer being used in the Linux kernel. WALE also implements differentiated services are recommended by IETF. A hash-based packet classifier is used to classify packets into one of 3 queues (Expedited Forwarding, Assured Forwarding and Best Effort). A simple priority scheduling has been implemented between the queues.

Version 2 has been implemented in the Generic Device Layer of the Linux Kernel. The kernel version is 2.2.19. WALE2 kernel patch can be downloaded here. An ncurses based front end has been implemented for setting and viewing various parameters of the bottleneck link.

GXemul is a machine emulator Im developing in my spare time.
GXemul project emulates processors and surrounding hardware components, in some cases well enough to allow unmodified "guest" operating systems to run inside the emulator as if they were running on a real machine.
MIPS:
- Several machine types are emulated well enough to run guest operating systems. NetBSD, OpenBSD, Linux, and even obscure things such as Ultrix and Sprite can run, to various degrees.
ARM:
- CATS is emulated well enough to run NetBSD and OpenBSD as guest OSes.
PowerPC:
- NetBSD/prep can run (experimental).
The emulator can be used for:
- experimenting with operating systems which you have not tried yet, or operating systems for hardware which you might not have access to,
- running guest operating systems for historical purposes, e.g. Ultrix or Sprite,
developing portable software, when you want yet another target platform to try to compile your software on (you can use GXemul to run a guest OS and compile your software inside that OS),
- development of new firmware or operating system code (but then you need to be aware of some limitations),
- educational purposes...
Enhancements:
- NetBSD/pmppc can now run in the emulator (with root on NFS).
- For ARM emulation (with NetBSD/cats, OpenBSD/cats, NetBSD/evbarm, or NetBSD/netwinder as the guest OS), the emulator does not use 100% of the hosts CPU if the guest OS is idle.

Paradise 2000 represents my bend of the Paradise Netrek client. Paradise 2000 Netrek Client is not a fork, because that would imply parallel development, but no one else has done anything with the client since about five years ago.
Paradise 2000 is in fact one of the most, if not the most, actively developed Netrek clients available today. It is for Linux (and FreeBSD) only, and is not open source*. Dont let the Paradise name fool you, it works just fine on standard bronco servers. Nobody has even played a game of Paradise Netrek for years!
The biggest new feature of the client, not found in any other, is the sound system. While the old Paradise client, Ted Turner, COW, and COW ports (Netrek1999,2000) have a simple sound effect system, its crap. Especially the one used by COW. The Paradise/Ted Turner one is better, and is partially written by me, though you wouldnt know that*.
The Paradise 2000 sound system has psychoacoustic stereo effects that place sounds based on where they happen. If someone on the left blows up, you can tell they are on the left just from the sound. The newest version of Paradise-2000 has a sound system with speech output using IBMs ViaVoice TTS. If a teammate sends a carrying message, the client will actually say something like, "F one carrying five to org."
Main features:
- See weapons on galactic map
- Auto-rotate galaxy to put playing teams on left side
- Dashboard timer to show repair or refit time remaining
- See the army count for the planet your are orbiting
- Remap your keys via the help window. Just push the key you want over the name of the function you want to assign to it.
- Use the same key for both bombing armies and picking armies. The client can tell by context with one would make sense.
- You can set configuration options to different values for different server types.
- Double buffering support for graphics. When turned on, eliminates flicker. Very useful for LCD monitors.
- Extensive support for enhanced observer mode:
- See all players tractors and pressors while observing.
- You can lock onto a cloaked player and observe them.
- All your ship stats will reflect the player you are observing. Even torps out, kills, and army capacity.
- Your ship and player letter dont get drawn on top of the player you are observings ship and letter.
- Observers wont have stats shown in your player list, cluttering it up unnecessarily..
- Stereo sound effects!
- Highly configurable speech synthesis!
- Option to omit the team letter of ships on the galactic. Just show 0 instead of F0, since you can tell the team by the color of the letter.
- Game score on hockey servers calculated and put on the galactic for easy reference.
- Cool looking streaking background stars when transwarping on Bronco servers.
- Flags on the dashboard gauges indicating the fuel/shields/hull needed to refit or transwarp.
- Single key transwarp on Bronco servers. Push - to automatically lock onto your base and warp to it!
- 19FLAGS protocol enhancement. Reduces messed up flags from packetloss. Hockey players, this will eliminate stuck tractors and pressors.
- Works with WindowMaker. Window manager delete buttons work.
- Hockey bug fix, puck doesnt cloak at warp 15 or 31.
- Support for short packets 2. Reduces bandwidth and improves playability with packetloss.
- Supports SBHOURS feature, see how many base hours someone has.
- Shrink phasers, like BRMH.
- Support for wheel mice. The wheel will scroll the message windows, and can be bound to actions like other mouse buttons.
- Re-enter the game after dying by pushing the spacebar, instead of clicking on the right team window. Faster and prevents selecting the wrong team on accident in 4v4 hockey games.
- 32 position ship bitmaps. Your ship rotations will look smoother.
- Small red circle around ship shows det radius.
- Tic marks to show exact ship heading.
- Arrow on puck to indicate direction.
- ID of player you are tractoring displayed next to your ship.
- Configure what columns are in the player list, both the one-column and two-column list. You can also change the width of the each field, so show fewer digits for instance.
- UDP portswap option that lets the client work through NAT firewalls, like Linux IP_MASQ, without a special module.
