Memory-mapped I/O ( MMIO) and port-mapped I/O ( PMIO) are two complementary methods of performing input/output (I/O) between the central processing unit (CPU) and peripheral devices in a computer (often mediating access via chipset ). An alternative approach is using dedicated I/O processors, commonly known as channels on mainframe computers ...
From a mathematical perspective, an eye pattern is a visualization of the probability density function (PDF) of the signal, modulo the unit interval (UI). In other words, it shows the probability of the signal being at each possible voltage across the duration of the UI. Typically a color ramp is applied to the PDF in order to make small ...
Hexagon is also known as QDSP6, standing for “sixth generation digital signal processor.”. According to Qualcomm, the Hexagon architecture is designed to deliver performance with low power over a variety of applications. [3] [4] Each version of Hexagon has an instruction set and a micro-architecture. These two features are intimately related.
Darlington Transistor (NPN-type) In electronics, a multi-transistor configuration called the Darlington configuration (commonly called as a Darlington pair) is a circuit consisting of two bipolar transistors with the emitter of one transistor connected to the base of the other, such that the current amplified by the first transistor is amplified further by the second one.
A wireless mesh network ( WMN) is a communications network made up of radio nodes organized in a mesh topology. It can also be a form of wireless ad hoc network. [1] A mesh refers to rich interconnection among devices or nodes. Wireless mesh networks often consist of mesh clients, mesh routers and gateways. Mobility of nodes is less frequent.
Advanced Vector Extensions 2 (AVX2), also known as Haswell New Instructions, [24] is an expansion of the AVX instruction set introduced in Intel's Haswell microarchitecture. AVX2 makes the following additions: expansion of most vector integer SSE and AVX instructions to 256 bits. Gather support, enabling vector elements to be loaded from non ...
Computer memory and Computer data storage types. Content-addressable memory ( CAM) is a special type of computer memory used in certain very-high-speed searching applications. It is also known as associative memory or associative storage and compares input search data against a table of stored data, and returns the address of matching data.
A Feynman diagram (box diagram) for photon–photon scattering: one photon scatters from the transient vacuum charge fluctuations of the other. Two-photon physics, also called gamma–gamma physics, is a branch of particle physics that describes the interactions between two photons. Normally, beams of light pass through each other unperturbed.
