Genesi

Genesi is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Genesi rather than just read about it. In short: Genesi is an international group of technology and consulting companies in the United States, Mexico and Germany. It is most widely known for designing and manufacturing ARM architecture and Power ISA-based computing devices.

Key takeaways

Genesi belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Genesi to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Genesi from memory before moving on to harder problems.

Reference excerpt

Genesi is an international group of technology and consulting companies in the United States, Mexico and Germany. It is most widely known for designing and manufacturing ARM architecture and Power ISA-based computing devices. The Genesi Group consists of Genesi USA Inc., Genesi Americas LLC, Genesi Europe UG, Red Efika, bPlan GmbH and the affiliated non-profit organization Power2People. As of 2012, Genesi was an official Linaro partner and its software development team was instrumental in moving Linux on the ARM architecture towards a wider adoption of the hard-float application binary interface, which was incompatible with most existing applications but provided large performance gains for many use cases as of 2012.

Products The main products of Genesi are ARM-based computers that were designed to be inexpensive, quiet and highly energy efficient, and a custom Open Firmware compliant firmware. All products can run a multitude of operating systems.

Current products Aura – A comprehensive abstraction layer for embedded and desktop devices, with UEFI and IEEE1275. Desktop systems with AGP or PCI/PCI Express may take advantage of an embedded x86/BIOS emulator providing boot functionality for standard graphics cards EFIKA MX53 EFIKA MX6

Discontinued products EFIKA MX Smarttop – A highly energy efficient and compact computing device (complete system) powered by a Freescale ARM iMX515 CPU EFIKA MX Smartbook – A 10″ smartbook (complete system) powered by the Freescale ARM iMX515 CPU High Density Blade – PowerPC based high density blade server Home Media Center – PowerPC based digital video recorder EFIKA 5200B – A small Open Firmware-based motherboard powered by a Freescale MPC5200B SoC processor with 128 MB RAM, a 44-pin ATA connector for a 2.5" hard drive, sound in/out, USB, Ethernet, serial port, and a PCI slot Open Client – thin clients available with Freescale's Power Architecture or ARM SoCs Pegasos – An Open Firmware-based MicroATX motherboard powered by a PowerPC G3/G4 microprocessor, featuring PCI slots, AGP, Ethernet, USB, DDR and FireWire Open Desktop Workstation – A Pegasos II based computer featuring a Freescale PowerPC 7447 processor. Complete specifications for the hardware are available through Genesi's PowerDeveloper.org website

Community support Genesi designed and maintains PowerDeveloper, an online platform for Genesi products and ARM products from other manufacturers. Via the PowerDeveloper Projects programs, hundreds of systems have been provided to the PowerDeveloper community so far, thereby supporting open source development in many countries. Linux distributions that directly benefited from the programs include but are not limited to Crux, Debian, Raspbian, Fedora, Gentoo, openSuSE and Ubuntu. Genesi once funded the development of the MorphOS operating system but shifted its focus towards Linux in 2004. However, as of 2011, Genesi remains the main supporter of the operating system and continues to actively support its user and developer communities via the MorphZone social platform, which features discussion forums, a digital library, a software repository and a bounty system.

Notes

Worked examples

Example 1 — a first encounter with Genesi

Start with the simplest possible case. Write down what Genesi claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Genesi before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Genesi ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Genesi

In research: Genesi appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Genesi in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Genesi is common in secondary-school and first-year university syllabi. It links to neighbouring topics ARM architecture, Amiga companies, Computer companies of the United States, so understanding it makes those chapters shorter.
In everyday life: Look for Genesi outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Genesi in simple terms?

Why does Genesi matter?

Because it connects several biology ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Genesi?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
