PICMG 1.3

PICMG 1.3 is a science 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 PICMG 1.3 rather than just read about it. In short: PICMG 1.3 is a PICMG specification which is commonly referred to as SHB Express. SHB Express is a modernization of PICMG 1.0 single-board computer specification.

Key takeaways

PICMG 1.3 belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect PICMG 1.3 to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of PICMG 1.3 from memory before moving on to harder problems.

Reference excerpt

PICMG 1.3 is a PICMG specification which is commonly referred to as SHB Express. SHB Express is a modernization of PICMG 1.0 single-board computer specification. SHB Express, or System Host Board – Express, uses the same physical form factor as PICMG 1.0 boards. The board-to-backplane interfaces are PCI Express instead of PCI and ISA, although the use of PCI remains as an option.

Key Features PCI Express: 20 PCI Express lanes including x16, x8, x4 and x1 PCI Express configuration are supported. PCI optional supported: 32Bit PCI Bus with up to 4 Master-capable Slots at the Backplane and with 33 MHz or optional 66 MHz. PCI-X Capabilities are also optional supported. additional I/O: up to 4 USB Connections, up to 2 SATA and up to 2 Ethernet (GBit) are also optional supported to the Backplane.

PICMG Status Adopted : 8/20/2005 Current Revision : 1.0

Worked examples

Example 1 — a first encounter with PICMG 1.3

Start with the simplest possible case. Write down what PICMG 1.3 claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 PICMG 1.3 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 PICMG 1.3 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 PICMG 1.3

In research: PICMG 1.3 appears in science 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 PICMG 1.3 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: PICMG 1.3 is common in secondary-school and first-year university syllabi. It links to neighbouring topics Open standards, PICMG standards, so understanding it makes those chapters shorter.
In everyday life: Look for PICMG 1.3 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 PICMG 1.3 in simple terms?

PICMG 1.3 is a PICMG specification which is commonly referred to as SHB Express. SHB Express is a modernization of PICMG 1.0 single-board computer specification.

Why does PICMG 1.3 matter?

Because it connects several science 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 PICMG 1.3?

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.
