Desktop and notebook computers - Measurement of energy consumption

IEC 62623:2012 covers personal computing products. It applies to desktop and notebook computers as defined in 4.1 that are marketed as final products and that are hereafter referred to as the equipment under test (EUT) or product. This standard specifies:
- a test procedure to enable the measurement of the power and/or energy consumption in each of the EUT's power modes;
- formulas for calculating the typical energy consumption (TEC) for a given period (normally annual);
- a majority profile that should be used with this standard which enables conversion of average power into energy within the TEC formulas;
- a system of categorisation enabling like for like comparisons of energy consumption between EUTs and a pre-defined format for the presentation of results.
This standard does not set any pass/fail criteria for the EUTs. Users of the test results should define such criteria. Keywords: Power consumption, Desktop computer, Notebook computer

IEC TR 62921:2016(Main)
Quantification methodology for greenhouse gas emissions for computers and monitors

IEC TR 62921:2016(E) provides specific guidance for the use of streamlining techniques that minimize cost and resources needed to complete greenhouse gas emissions quantifications. In addition, the product category rules (PCR) section of this Technical Report recommends "state-of-the-art" process and data assumptions in order to reduce uncertainty. Lastly, this Technical Report provides an example of how a calculation could be performed.

Photovoltaic devices - Part 5: Determination of the equivalent cell temperature (ECT) of photovoltaic (PV) devices by the open-circuit voltage method

IEC 60904-5:2011 describes the preferred method for determining the equivalent cell temperature (ECT) of PV devices (cells, modules and arrays of one type of module), for the purposes of comparing their thermal characteristics, determining NOCT (nominal operating cell temperature) and translating measured I-V characteristics to other temperatures. The main technical changes with regard to the previous edition are as follows:
- added method on how to extract the input parameters;
- rewritten method on how to calculate ECT;
- reworked formulae to be in line with IEC 60891.

IEC TR 61838:2009(Main)
Nuclear power plants - Instrumentation and control important to safety - Use of probabilistic safety assessment for the classification of functions

IEC/TR 61838:2009 provides a survey of some of the methods by which probabilistic risk assessment results can be used to establish "risk-based" classification criteria, so as to allow FSEs to be placed within the four categories established within IEC 61226. The safety principles and the usefulness of a risk-based approach to classification are discussed and a description of four different approaches is presented. The main technical changes in this second edition with regard to the previous edition are as follows:
- to update the references and the terminology;
- to take into account the progress done since edition 1.

VME64bus - Specification

The VMEbus specification defines an interfacing system used to interconnect microprocessors, data storage and peripheral control devices in a closely-coupled hardware configuration. Its objectives include allowing communication between devices on the VMEbus without disturbing the internal activities of other devices on the VMEbus, allowing a broad range of design latitude so that the designer can optimize cost and/or performance without affecting system compatibility, and providing a system where performance is primarily device-limited rather than system-interface-limited.  Note that this publication is available not in paper form but as a CD-ROM.

Information technology - Scalable Coherent Interface (SCI)

The scalable coherent interface (SCI) provides computer-bus-like services but, instead of a bus, uses a collection of fast point-to-point unidirectional links to provide the far higher throughput needed for high-performance multiprocessor systems. SCI supports distributed, shared memory with optional cache coherence for tightly coupled systems, and message-passing for loosely coupled systems. Initial SCI links are defined at 1 Gbyte/s (16-bit parallel) and 1 Gb/s (serial). For applications requiring modular packaging, an interchangeable module is specified along with connector and power. The packets and protocols that implement transactions are defined and their formal specification is provided in the form of computer programs. In addition to the usual read-and-write transactions, SCI supports efficient multiprocessor lock transactions. The distributed cache-coherence protocols are efficient and can recover from an arbitrary number of transmission failures. SCI protocols ensure forward progress despite multiprocessor conflicts (no deadlocks or starvation).

Information technology - Microprocessor systems - Heterogeneous InterConnect (HIC) (Low-Cost, Low-Latency Scalable Serial Interconnect for Parallel System Construction)

The construction of high-performance systems with parallel communications, parallel processing, and/or parallel I/O demands a fast, low-cost, low-latency interconnect. It must be fast and low-latency, otherwise it will be the limiting factor in system performance; and it must be low-cost, or it will dominate the system cost. This standard has been developed to complement recent technical developments of highly integrated, low-power interconnect technology implemented in high-volume commodity VLSI processes, and to exploit the simplifications in encodings and protocols resulting from the use of relatively reliable media over relatively short distances.

SBus - Chip and module interconnect bus

An input/output expansion bus with a 32- or 64-bit width is described in this standard. The SBus is designed for systems requiring a small number expansion ports. SBus Cards may be connected to a standard Sbus Connector mounted on the motherboard. SBus Devices may also be attached to the SBus directly on the system's motherboard. The dimensions of the SBus Card are 83,8 mm by 146,7 mm, making the cards appropriate for small computer systems that make extensive use of highly integrated circuits. The SBus Cards are designed to be installed in a plane parallel to the system's motherboard as mezzanine cards. They are designed to provide connections for devices external to the computer system through an exposed back panel. The form factor is useful in Futurebus+, VMEbus, desktop computers, and similar applications. The SBus has the capability of transferring data at rates up to 168 Mbytes/s, depending on the implementation options selected. SBus Cards may either serve as Masters on the bus, providing all virtual address information as well as the data to be transferred, or they may serve as Slaves on the bus, providing data transfer according to the requirements of some other SBus Master. The SBus Master for a data transfer is selected by an arbitration process managed by the single SBus Controller on the SBus. The SBus Controller provides a virtual to physical address translation service.
