Computer-on-module
A computer-on-module (COM) is a type of single-board computer (SBC), a subtype of an embedded computer system. An extension of the concept of system on chip (SoC) and system in package (SiP), COM lies between a full-up computer and a microcontroller in nature. It is very similar to a system on module (SOM). Design COMs are complete embedded computers built on a single circuit board. The design is centered on a microprocessor with RAM, input/output controllers and all other features needed to be a functional computer on the one board. However, unlike a single-board computer, the COM usually lacks the standard connectors for any input/output peripherals to be attached directly to the board. The module usually needs to be mounted on a carrier board (or "baseboard") which breaks the bus out to standard peripheral connectors. Some COMs also include peripheral connectors. Some can be used without a carrier. A COM solution offers a dense package computer system for use in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ESMexpress
ESMexpress is a very compact computer-on-module (COM) standard. It is a complete processor module that currently supports several low-power Intel and PowerPC platforms. Apart from a CPU component, every module also includes memory and a range of serial communication interfaces such as PCI Express, Gigabit Ethernet, USB, SATA, SDVO, LVDS and HD audio. These interfaces are defined in the form factor's specification, and signals are assigned to two 120-pin connectors. This fixed pin mapping ensures that different ESMexpress modules can be exchanged more easily. Consequently, ESMexpress typically does not have an onboard FPGA. The idea behind this is to implement very specialized functions in an FPGA on the COM's carrier board to ease upgrades of the system CPU through exchange of the ESMexpress module. The ESMexpress standard includes only one form factor: 95 x 125 mm. The most important specialty of this computer-on-module is its surrounding mechanical concept, which was designed for e ...

Qseven
Qseven, a computer-on-module (COM) form factor, is a small, highly integrated computer module that can be used in a design application much like an integrated circuit component. It is smaller than other computer-on-module standards such as COM Express, ETX or XTX and is limited to very low power consuming CPUs. The maximum power consumption should be no more than 12 watts. Specification The name comes from the word "quadratic" due to the square shape of the original module, 70mm on a side. It was first proposed in 2008 by Congatec. Other companies based in Europe such as Kontron adopted the standard, but after a few years it had not yet been popular in the USA. The Qseven specification is hosted by the Standardization Group for Embedded Technologies (SGET), which took over from the original Qseven consortium in 2013.. The revision 2.0 was released September 9, 2012, and 2.1 on February 25, 2016. The Qseven design guide provides information for designing a custom system carrie ...

Smart Mobility Architecture
Smart Mobility Architecture (SMARC) is a computer hardware standard for computer-on-modules (COMs). SMARC modules are specifically designed for the development of extremely compact low-power systems, such as mobile devices. Specification The SMARC hardware specification V1.0 was published by the Standardization Group for Embedded Technologies (SGET). SGET had its first meeting in 2012, headed by Engelbert Hörmannsdorfer. The specification is freely available as a download on the SGET website. Generally, SMARC modules are based on ARM architecture processors, they can, however, also be fitted with other low-power system on a chip (SoC) architectures, like, for example, ones based on x86 processors. Typically, SMARC modules’ power requirement is in the range of a few watts. Computer-on-modules integrate the core function of a bootable computer, as well as additional circuitry, including DRAM, boot-flash, voltage distribution, Ethernet and display transmitter. The modules are d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Single-board Computer
A single-board computer (SBC) is a complete computer built on a single circuit board, with microprocessor(s), memory, input/output (I/O) and other features required of a functional computer. Single-board computers are commonly made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computers or portable computers integrate all their functions onto a single printed circuit board. Unlike a desktop personal computer, single board computers often do not rely on expansion slots for peripheral functions or expansion. Single board computers have been built using a wide range of microprocessors. Simple designs, such as those built by computer hobbyists, often use static RAM and low-cost 32- or 64-bit processors like ARM. Other types, such as blade servers, would perform similar to a server computer, only in a more compact format. A computer-on-module is a type of single-board computer made to plug into a ca ...

ETX (form Factor)
ETX, standing for Embedded Technology eXtended, is an integrated and compact computer-on-module (COM) form factor, which can be used in a design application much like an integrated circuit component. Each ETX COM integrates core CPU and memory functionality, the common I/O of a PC/AT (serial, parallel, etc.), USB, audio, graphics, and Ethernet. All I/O signals as well as a full implementation of ISA and PCI buses are mapped to four high-density, low-profile connectors on the bottom side of the module. ETX boards are available with AMD Geode, VIA, Intel Atom, Pentium, Celeron and Core Duo processors. XTX offers a 75% pin-compatible upgrade path to ETX standard. XTX drops the ISA bus and adds PCI-Express, SATA, and LPC. COM Express was released in 2005 from PICMG. History The Embedded Technology eXtended (ETX) specification, first developed by Kontron (formerly *JUMPtec) in early 2000. In April 2006, the members of the ETX Industrial Group released the next generation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embedded System Module
Embedded System Module, or ESM, is a compact computer-on-module (COM) standard. An ESM module typically includes a CPU processor, memory, module-specific I/O interfaces and a number of basic front I/O connectors. They can be plugged on a carrier board or be used as a stand-alone processor card. If the ESM module is plugged on a carrier, it relies on the standard PCI bus as a board-to-board interface. In this case two connectors create a link to the carrier. While the "J1" connector provides a specified PCI connection, the "J2" connector brings I/O signals from the ESM module to the carrier, which then includes all necessary connectors. The signal assignment of J2 is not fixed but can be completely customized, although there are reserved pins for a 64-bit PCI bus interface. A third connector, "J3", is used for additional I/O signals if the ESM module has no front I/O. The signal assignment of this connector is fixed to support a special set of I/O functions. A large part of the I/O f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CoreExpress
CoreExpress modules are complete computer-on-module (COM) highly integrated, compact computers that can be used in an embedded computer board design, much like an integrated circuit component. COMs integrate CPU, memory, graphics, and BIOS, and common I/O interfaces. The interfaces are modern, using only digital buses such as PCI Express, Serial ATA, Ethernet, USB, and HD audio (Intel High Definition Audio). All signals are accessible on a high-density, high-speed, 220-pin connector. Although most implementations use Intel processors, the specification is open for different CPU modules. CoreExpress modules are mounted on a custom carrier board, containing the peripherals required for the specific application. In this way, small but highly specialized computer systems can be built. The CoreExpress form factor was originally developed by LiPPERT Embedded Computers and standardized by the Small Form Factor Special Interest Group in March 2010.

COM Express
COM Express, a computer-on-module (COM) form factor, is a highly integrated and compact computer that can be used in a design application much like an integrated circuit component. Each module integrates core CPU and memory functionality, the common I/O of a PC/AT, USB, audio, graphics ( PEG), and Ethernet. All I/O signals are mapped to two high density, low profile connectors on the bottom side of the module. COM Express employs a mezzanine-based approach. The COM modules plug into a baseboard that is typically customized to the application. Over time, the COM Express mezzanine modules can be upgraded to newer, backwards-compatible versions. COM Express is commonly used in Industrial, military, aerospace, gaming, medical, transportation, Internet of things, and general computing embedded applications. History The COM Express standard was first released in 2005 by the PCI Industrial Computer Manufacturers Group (PICMG). It defined five module types, each implementing differen ...

Semiconductor Intellectual Property Core
In electronic design, a semiconductor intellectual property core (SIP core), IP core, or IP block is a reusable unit of logic, cell, or integrated circuit layout design that is the intellectual property of one party. IP cores can be licensed to another party or owned and used by a single party. The term comes from the licensing of the patent or source code copyright that exists in the design. Designers of application-specific integrated circuits (ASIC) and systems of field-programmable gate array (FPGA) logic can use IP cores as building blocks. History The licensing and use of IP cores in chip design came into common practice in the 1990s. There were many licensors and also many foundries competing on the market. In 2013, the most widely licensed IP cores are from Arm Holdings (43.2% market share), Synopsys Inc. (13.9% market share), Imagination Technologies (9% market share) and Cadence Design Systems (5.1% market share). Types of IP cores The use of an IP core in chip ...

Time To Market
In commerce, time to market (TTM) is the length of time it takes from a product being conceived until its being available for sale. The reason that time to market is so important is since being late erodes the addressable market into which producers have to sell their product. A common assumption is that TTM matters most for first-of-a-kind products, but actually a late product launch in any industry can negatively impact revenues—from reducing the window of opportunity to generate revenues to causing the product to become obsolete faster. Measuring TTM There are no standards for measuring TTM, and measured values can vary greatly. First, there is great variation in how different organizations define the start of the period. For example, in the automotive industry the development period starts when the product concept is approved. Other organizations realize that little will happen until the project is staffed, which can take a long time after approval if developers are tied ...
