Digital electronicsDigital electronics is a field of electronics involving the study of digital signals and the engineering of devices that use or produce them. This is in contrast to analog electronics and analog signals. Digital electronic circuits are usually made from large assemblies of logic gates, often packaged in integrated circuits. Complex devices may have simple electronic representations of Boolean logic functions. The binary number system was refined by Gottfried Wilhelm Leibniz (published in 1705) and he also established that by using the binary system, the principles of arithmetic and logic could be joined.
Broadwell (microarchitecture)Broadwell is the fifth generation of the Intel Core Processor. It is Intel's codename for the 14 nanometer die shrink of its Haswell microarchitecture. It is a "tick" in Intel's tick–tock principle as the next step in semiconductor fabrication. Like some of the previous tick-tock iterations, Broadwell did not completely replace the full range of CPUs from the previous microarchitecture (Haswell), as there were no low-end desktop CPUs based on Broadwell.
Kentsfield (microprocessor)Kentsfield is the code name of the first Intel desktop Core 2 Quad and quad-core Xeon CPUs, released on November 2, 2006. The top-of-the-line Kentsfields were Core 2 Extreme models numbered QX6x00, while the mainstream Core 2 Quad models were numbered Q6x00. All of them featured two 4 MiB L2 caches. The mainstream 65 nanometer Core 2 Quad Q6600, clocked at 2.4 GHz, was launched on January 8, 2007 at US851(reducedtoUS530 on April 7, 2007). Multi-channel memory architectureIn the fields of digital electronics and computer hardware, multi-channel memory architecture is a technology that increases the data transfer rate between the DRAM memory and the memory controller by adding more channels of communication between them. Theoretically, this multiplies the data rate by exactly the number of channels present. Dual-channel memory employs two channels. The technique goes back as far as the 1960s having been used in IBM System/360 Model 91 and in CDC 6600.
Signoff (electronic design automation)In the automated design of integrated circuits, signoff (also written as sign-off) checks is the collective name given to a series of verification steps that the design must pass before it can be taped out. This implies an iterative process involving incremental fixes across the board using one or more check types, and then retesting the design. There are two types of sign-off's: front-end sign-off and back-end sign-off. After back-end sign-off, the chip goes to fabrication.
Coffee LakeCoffee Lake is Intel's codename for its eighth-generation Core microprocessor family, announced on September 25, 2017. It is manufactured using Intel's second 14 nm process node refinement. Desktop Coffee Lake processors introduced i5 and i7 CPUs featuring six cores (along with hyper-threading in the case of the latter) and Core i3 CPUs with four cores and no hyperthreading. On October 8, 2018, Intel announced what it branded its ninth generation of Core processors, the Coffee Lake Refresh family.
Golden AgeThe term Golden Age comes from Greek mythology, particularly the Works and Days of Hesiod, and is part of the description of temporal decline of the state of peoples through five Ages, Gold being the first and the one during which the Golden Race of humanity (χρύσεον γένος chrýseon génos) lived. After the end of the first age was the Silver, then the Bronze, after this the Heroic age, with the fifth and current age being Iron. By extension, "Golden Age" denotes a period of primordial peace, harmony, stability, and prosperity.
SpeedStepEnhanced SpeedStep is a series of dynamic frequency scaling technologies (codenamed Geyserville and including SpeedStep, SpeedStep II, and SpeedStep III) built into some Intel microprocessors that allow the clock speed of the processor to be dynamically changed (to different P-states) by software. This allows the processor to meet the instantaneous performance needs of the operation being performed, while minimizing power draw and heat generation. EIST (SpeedStep III) was introduced in several Prescott 6 series in the first quarter of 2005, namely the Pentium 4 660.
Golden age (metaphor)A golden age is a period considered the peak in the history of a country or people, a time period when the greatest achievements were made. The term originated from early Greek and Roman poets, who used it to refer to a time when mankind lived in a better time and was pure (see Golden Age). The ancient Greek poet Hesiod introduced the term in his Works and Days, when referring to the period when the "Golden Race" of man lived.
Analog synthesizerAn analog (analogue) synthesizer (or synthesiser) is a synthesizer that uses analog circuits and analog signals to generate sound electronically. The earliest analog synthesizers in the 1920s and 1930s, such as the Trautonium, were built with a variety of vacuum-tube (thermionic valve) and electro-mechanical technologies. After the 1960s, analog synthesizers were built using operational amplifier (op-amp) integrated circuits, and used potentiometers (pots, or variable resistors) to adjust the sound parameters.
