System bus. A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity ...
Many manufacturers publish the frequency of the front-side bus in MHz, but marketing materials often list the theoretical effective signaling rate (which is commonly called megatransfers per second or MT/s). For example, if a motherboard (or processor) has its bus set at 200 MHz and performs 4 transfers per clock cycle, the FSB is rated at 800 ...
Bus (computing) In computer architecture, a bus [1] (historically also called data highway [2] or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
CPU multiplier. In computing, the clock multiplier (or CPU multiplier or bus/core ratio) sets the ratio of an internal CPU clock rate to the externally supplied clock. This may be implemented with phase-locked loop (PLL) frequency multiplier circuitry. A CPU with a 10x multiplier will thus see 10 internal cycles for every external clock cycle.
HyperTransport ( HT ), formerly known as Lightning Data Transport, is a technology for interconnection of computer processors. It is a bidirectional serial / parallel high- bandwidth, low- latency point-to-point link that was introduced on April 2, 2001. [1] The HyperTransport Consortium is in charge of promoting and developing HyperTransport ...
I²C-bus = 3 mA; SMBus ‘high power’ devices and I²C-bus devices will work together if the pull-up resistor is sized for 3 mA. Frequency (F MAX and F MIN. The SMBus clock is defined from 10 to 100 kHz while I²C can be 0–100 kHz, 0–400 kHz, 0–1 MHz and 0–3.4 MHz, depending on the mode.
In an alternating current (AC) electric power system, synchronization is the process of matching the frequency, phase and voltage of a generator or other source to an electrical grid in order to transfer power. If two unconnected segments of a grid are to be connected to each other, they cannot safely exchange AC power until they are ...
The bus bandwidth therefore only has an effect on the number of channels that can be sent at a time, not the speed or latency of the transmission. Low speed (LS) rate of 1.5 Mbit/s is defined by USB 1.0. It is very similar to full-bandwidth operation except each bit takes 8 times as long to transmit.
