Embedded System Terminology - E
| Earliest Deadline First (EDF) - A real-time, preemptive OS scheduling scheme in which tasks are scheduled according to their deadline, duration, and frequency. |
| Effective Address - The memory address generated by the software. This is the address that is then translated into the physical address of the actual hardware. |
| Electrically Erasable Programmable Read Only Memory (EEPROM) - A type of ROM which can be erased and reprogrammed more then once, the number of times of erasure and re-use depending on the EEPROM. The contents of EEPROM can be written and erased “in bytes” without using any special devices. This means the EEPROM can stay on its residing board, and the user can connect to the board interface to access and modify EEPROM. |
| Electricity - Energy generated by the flow of electrons through a conductor. |
| Electron - A negatively charged subatomic particle. |
| Embedded C - A subset of the C programming language that is optimized for embedded systems use and supported by some compiler vendors. |
| Embedded C++ - A subset of the C++ programming language that is optimized for embedded systems use and supported by some compiler vendors. |
| Embedded System - A system in which the computer (generally a microcontroller or microprocessor) is included as an integral part of the system. |
| Emitter - One of three terminals of a bipolar transistor. |
| Emulator - Any debugging tool that pretends to be a system resource and adds additional functionality or remote visibility. |
| Encoder - A device that encodes (translates) a set of data into another set of data. |
| Endianness - See Byte Order. |
| Energy - The amount of work performed that can be measured in units of joules (J) or watts * Time. |
| Erasable Programmable Read Only Memory (EPROM) - A type of ROM that can be erased more than one time using other devices that output intense short wavelength, ultraviolet light into the EPROM package’s built-in transparent window. |
| Ethernet - One of the most common LAN protocols, implemented at physical and data link layers of the OSI model. |
| Evaluation Kit Evaluation Kit (EV Kit, Development Kit) - A printed circuit board with an integrated circuit and support components to produce a working circuit for evaluation and development. Most Evaluation Kits are fully assembled and tested. |
| Extended Data Out Random Access Memory (EDO RAM) - A type of RAM commonly used as main and/or video memory; it is a faster type of RAM that can send a block of data and fetch the next block of data simultaneously. |
| Executable - A file containing object code that is ready for execution on the target. All that remains is to place the object code into a ROM or download it via a debugging tool. |
