Linux Drivers
Linux ( ) is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution (distro), which includes the kernel and supporting system software and libraries—most of which are provided by third parties—to create a complete operating system, designed as a clone of Unix and released under the copyleft GPL license. Thousands of Linux distributions exist, many based directly or indirectly on other distributions; popular Linux distributions include Debian, Fedora Linux, Linux Mint, Arch Linux, and Ubuntu, while commercial distributions include Red Hat Enterprise Linux, SUSE Linux Enterprise, and ChromeOS. Linux distributions are frequently used in server platforms. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses and recommends the name "GNU/Linux" to emphasize t ...

Tux (mascot)
Tux is a penguin character and the official mascot of the Linux kernel. Originally created as an entry to a Linux logo competition, Tux is the most commonly used icon for Linux, although different Linux distribution, Linux distributions depict Tux in various styles. The character is used in many other Linux programs and as a general symbol of Linux. History Origins The concept of the Linux brand character being a penguin came from Linus Torvalds, the creator of Linux. According to Jeff Ayers, Linus Torvalds had a "fixation for flightless, fat waterfowl" and Torvalds claims to have contracted "penguinitis" after being nibbled by a little penguin on a visit to the National Zoo & Aquarium in Canberra, Australia. Linus spoke at the 1994 AUUG Conference (5–9 Sept, Melbourne) as part of a "World Tour" to Belgium, Australia, Singapore and elsewhere, mentioning in ''Linux Journal'' he was bitten by a penguin at Canberra Zoo, not at Phillip Island, Victoria, by a (shy) wild penguin.

M·CORE
M·CORE is a low-power, RISC-based microcontroller architecture developed by Motorola (subsequently Freescale, now part of NXP), intended for use in embedded systems. Introduced in late 1997, the architecture combines a 32-bit internal data path with 16-bit 16-bit microcomputers are microcomputers that use 16-bit microprocessors. A 16-bit register can store 216 different values. The range of integer values that can be stored in 16 bits depends on the integer representation used. With the two ... instructions, and includes a four-stage instruction pipeline. Initial implementations used a 360nm process and ran at 50 MHz. M·CORE processors employ a von Neumann architecture with shared program and data bus—executing instructions from within data memory is possible. Motorola engineers designed M·CORE to have low power consumption and high code density. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SuperH
SuperH (or SH) is a 32-bit reduced instruction set computing (RISC) instruction set architecture (ISA) developed by Hitachi and currently produced by Renesas. It is implemented by microcontrollers and microprocessors for embedded systems. At the time of introduction, SuperH was notable for having fixed-length 16-bit instructions in spite of its 32-bit architecture. Using smaller instructions had consequences: the processor register, register file was smaller and instructions were generally two-operand format. However for the market the SuperH was aimed at, this was a small price to pay for the improved memory and processor cache efficiency. Later versions of the design, starting with SH-5, included both 16- and 32-bit instructions, with the 16-bit versions mapping onto the 32-bit version inside the CPU. This allowed the machine code to continue using the shorter instructions to save memory, while not demanding the amount of instruction decoding logic needed if they were completely ...
