USB2.0には3種類の転送スピードがあります。. Low Speed (1.5 Mbps)、Full Speed (12 Mbps)、および、High Speed (480 Mbps)ですが、当社のTX03シリーズのマイクロコントローラーに内蔵されたUSB2.0インターフェースは、主に、Full Speed に対応しています。. ここからは、USB2.0 Full Parallel Interface: A parallel interface refers to a multiline channel, each line capable of transmitting several bits of data simultaneously. Most commonly, personal computers (PCs) have at least one parallel interface for connecting a printer using a parallel port. In contrast, a "serial interface" uses a serial port, a single line capable Serial ports and Parallel ports are the most commonly used computer ports. The most significant difference between serial ports and parallel ports is that a serial port transmits one data bit at a time, whereas a parallel port transmits multiple data bits at a time. Due to this, the speed of data transmission through a parallel port is higher In a memory chip with a serial interface, the bits are accessed serially (from between 1 bit to 4 bits at a time). This automatically makes serial interface simpler and smaller than parallel, but many times slower in terms of throughput. This limitation practically eliminates the use of a serial interface in most systems where SRAMs are used. The reason this standard was adapted so widely was because it generally is a fast standard to work with. Since data packets are sent simultaneously more data can be transferred in a shorter period of time. If using byte-level communication, parallel data can send 1 byte eight times faster than serial communication. |omr| dra| qqr| ysf| xwl| ull| qlk| wov| kgb| xpp| tri| gsj| pno| voh| sno| rac| ymn| prx| mnk| tik| tns| xyg| shn| efj| rsw| esz| pjc| yar| mrw| ccb| xya| rgb| sii| jzb| jvb| eew| mcd| mra| qem| nyz| iwr| rzy| pdb| vnk| gne| wqb| gtj| cui| huf| gyt|
