RFID Radio Frequency Identification System ID (Radio Frequency Identification System)
RFID is an advanced Radio Frequency Identification technology, through the goods of the microchip "tags" can be connected to the computer network where information used to identify, track and confirm the state of commodities.
Each label will be launching a unique ID code, then the provision of adequate product information. RFID activity of (activity) from the use of radio scanners to monitor the status of each chip in order to identify, track, sort and identify a variety of objects, whether human, vehicle, merchandise and so on.
According to ITRI data, RFID consists of Inquiry A device (Transponder) and readers (Reader) two kinds of devices. Inquiry A device, such as the card or label, a passive version is a reply device, when the system starts from the reader produce specific frequencies of radio signals A device to stimulate exercise programs within the chip, thereby generate RF waves, and to the memory of the identification code (ID Code) returns the reader, and then followed by decoding by the host computer to determine complete recognition.
Because RFID is a non-contact technology, do not like a traditional magnetic stripe-like, must have direct contact with the reader, can be ruled out because of adverse contact with sensor identification arising from an unknown.
RIP
1. ROUTING INFORMATION PROTOCOL: two routers (ROUTER) exchanged between the tracks around the table (ROUTING TABLE) using the protocol (PROTOCOL), RFC document number is 1058
.2. RASTER IMAGE PROCESSOR: a way to vector (VECTOR) was converted into a point Array Map (BITMAP) for the output of the hardware and software systems.
RISC reduced instruction set (Reduce Instruction Set Computer)
As a processor architecture, and traditional complex instruction set (CISC) different, RISC instruction format, unity, and few varieties, easy to learn, design and development program.
Used the computer central processing unit can be divided into RISC and CISCT wo, during which the difference in storage in the CPU of the Instruction Set(Instruction set) the number of different.
As the RISC instruction streamlined to improve processor performance, but the relative need for more complex external programming. RISC instruction within the framework of about 90% of the direct delivery of hardware to complete, with only 10% of the software instructions are denominated in combination manner.
Compared with traditional computers, a number of complex instructions often have to deal with cycles to complete, but the computer was able to RISC in a single processing environment to perform many complex instructions, so that many applications can be faster and more efficient to achieve. Based on this technology offers simple and rapid characteristics, has now been necessary for high-performance built-in computer architecture.
RISC architecture is more streamlined, unlike the CISC limited by too many steps, resulting in idle cell circuit to wait longer, to the detriment of parallel processing applications. Solely on the performance ratio, RISC than CISC addressing means less processing performance and speed is clearly superior to CISC architectures. However, in the instruction execution time, RISC over CISC slower speed of execution.
In addition, RISC architecture, program developers must be careful to choose the appropriate compiler, not only re-write the application software before the code continues to expand, will be spent (need) more, faster memory space. At this stage, RISC systems used for non-camp, high-performance x86 microprocessors, manufacturers, including APPLE, SGI / MIPS, IBM, SUN, HP and so on. |
