k10ctl is a P-State utility for AMD family 10h (aka K10) processors. It can modify the P-States, i.e. alter processor and the northbridge frequencies and voltages, set or change the P-State, and read out frequency and voltage information. The main purpose of k10ctl is overclocking or "undervolting" the CPU and to configure Cool'n'Quiet settings.
c2ctl is a frequency and voltage modification utility mainly intended for Intel Core 2 and Core CPUs. It should also work for other CPUs (namely processors with SpeedStep). The utility can also enable SpeedStep (e.g. if it was disabled by the BIOS due to overclocking) and read out frequency and voltage information. The main purpose of c2ctl is overclocking or "undervolting" and to enable SpeedStep.
SoCLib is a library of pluggable SystemC cycle-accurate and transaction-level components. The library contains many types of models: processor cores (MIPS32, PPC405, ARM-v6k, Nios2, MicroBlaze, lm32, etc.), memory types, devices (block device, UART, frame buffer, etc.) and network-on-chip models. SoCLib can be used to create a complete system-on-chip hardware design, as well as for testing and evaluating embedded operating systems and applications. NetBSD, MutekH, and other dedicated systems are ported to the SoCLib hardware simulator. A Linux port is an ongoing project.
Emma the Emulator is a generic 16-bit CPU emulator written as an educational tool. It supports a basic instruction set, has two registers and a program counter pointing to a heap structure which can be resized at compile time, and has a basic stack (not linked to the heap in any way), a flag register, and an internal "error number" for debugging purposes. There is also a "debug" mode which adds a lot of runtime debugging information and causes the program to sleep for 1 second between operations.
I-Nex gathers information for hardware components available on your system and displays it using an user interface similar to the popular Windows tool CPU-Z. It can display information for CPU, GPU, Motherboard, Sound, Hard disks, RAM, Network, and USB, as well as some system information like the hostname, Linux distribution and version, Xorg, GCC, and GLX versions, and Linux Kernel. It can also generate a report on which you can select what to include and optionally send the report to a service such as Pastebin (and others). It also features an option to take a screenshot of the I-Nex window directly from the application.
