The Rabbit 2000 is a high-performance 8-bit microcontroller designed by Rabbit Semiconductor for embedded system applications. Its extensive integrated feature set and glueless architecture facilitate rapid hardware design, and its C-friendly instruction set permits efficient development of complex applications for embedded systems.

Random Bit Generator

Device or algorithm that outputs a sequence of statistically independent and unbiased bits


Resin is a web server and Java application server from Caucho Technology. In addition to Resin (GPL), Resin Pro is available for enterprise and production environments. Resin supports the Java EE standard as well as a mod_php/PHP like engine called Quercus.


  • Algebraic structure ⟨S, ∗1, ∗2⟩
    • A set S
    • Two associative binary operations ∗1 and ∗2
    • ⟨S, ∗1⟩ is a commutative (Abelian) group with identity element e1
    • ⟨S, ∗2⟩ is a monoid with identity element e2
    • The operation ∗2 is distributive over the operation ∗1


Reduced instruction set computing, or RISC (pronounced 'risk'), is a CPU design strategy based on the insight that a simplified instruction set provides higher performance when combined with a microprocessor architecture capable of executing those instructions using fewer microprocessor cycles per instruction.


RS-232 is a standard for serial communication transmission of data. It formally defines the signals connecting between a DTE (data terminal equipment) such as a computer terminal, and a DCE (data circuit-terminating equipment or data communication equipment), such as a modem.


TIA-485-A, also known as ANSI/TIA/EIA-485, TIA/EIA-485, EIA-485 or RS-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced and multipoint systems are supported.
