CMOS

CMOS (Complementary Metal Oxide Semiconductor) is a technology for constructing integrated circuits and, by extension, all components manufactured using this technology.

DDR2

DDR2 or DDR2 SDRAM (Double Data Rate two Synchronous Dynamic Random Access Memory ) is the second DDR dynamic memory type generation for personal computer. This technology is a part of dynamic memory family SDRAM, that is one of the DRAM memory multiple version. The DDR2-SDRAM operates the transfer on the rising edge and falling edge of clock pulses "dual pumping". Compared to DDR, at equivalent operating frequency, it has a data rate twice as high. This memory is more appropriate to transferring large amount of data.

FPGA

FPGA (Field Programmable Gate Array), is a logic integrated circuit design to be configured after manufacturing. It contains lots of ''logic block'' freely ''wired.together''. To program an FPGA, it is necessary to use an Hardware Development Language like VHDL, netlist of which will be compiled for a configuration file for the FPGA.

HDL

HDL (Hardware Description Language) is a computer language for formal description of electronic circuits. It may describe the functions performed by the circuit (behavioral description) or logic gates used by the circuit (structural description).

IP

IP (Intellectual Property ), within the FPGA configuration, is a compiled hardware description for configuring an FPGA so that it can perform a particular type of data processing.
Not to be confused with IP (Internet Protocol) of TCP/IP.

Pipe or named pipe

A pipe is a communication mechanism that allows for communication between processes as a continuous stream of bytes.
The named pipe is a pipe that exists in the file system, which is open through a reference.

Process (computer)

A computer process is a complex operation executable by a computer as defined by:
a set of instructions to execute (a program), sometimes located in a read only memory ( especially common in embedded systems), but usually loaded from a mass memory to RAM;
address space in memory to store the stack, the working data, and more ;
possibly other resources such as file descriptors, network ports, and more.
The execution of a process takes some time, with a beginning and (sometimes) end. A process can be started by a user through a peripheral or by another process.

Socket

Socket is a computer term that can have multiple meanings depending on whether it is used in software or hardware. In our case, we use it in software. In this case, it can be understanded as "network connection".
Then it is a software interface with the operating system services, through which a developer will operate easily and uniformly the services of a network protocol. We can give it a name.

SRAM

SRAM (Static Random Access Memory) is a type of RAM using flip-flops to store the data. Unlike the DRAM, there is no need to periodically refresh its content. However, as dynamic memory, it is volatile. It can not do without power supply otherwise the information will be deleted forever.
The static memory is more expensive but faster and consumes less power than DRAM. It is therefore dedicated to applications which require a short access time, or a low power consumption. Thus, it is found in caches memory and buffers, as well as in embedded applications.

USB 2.0

USB (Universal Serial Bus) is a standard for which a computer bus in serial transmission is used to connect computer peripherals to a computer.
The USB can hot-plug peripherals and in its USB 2.0 version, it allows for theoretical speeds up to 480 Mbit/s or 60 MB/s.

VHDL

VHDL (VHSIC Hardware Description Language) is a Hardware Description Language (HDL) intended to represent the behavior and the architecture of a digital electronic system.

VHSIC

VHSIC (Very High Speed Integrated Circuits) was a 1980s U.S. government program to develop very high speed integrated circuits. This initiative is the origin of many advances in the field of microelectronics, both on the lithographic process, the assembly that the CAD tools. This program is the source of VHDL.
