Description of the invention: [Technical field to which the invention pertains] The invention relates to computer peripheral products, in particular to a data copying machine 0: 5 [prior art] ' Today, a personal computer (PC) It includes a desktop type and a notebook computer. It is a fairly common electronic product, and its computing speed and data storage are not the same. Basically, a computer contains components such as a host, a screen, a keyboard, and a mouse. The computer mainframe includes a central processing state, a memory, a large number of storage devices, a power supply, and the like. Mass storage devices include floppy disks, hard dlsks, CD-ROMs, CD-RWs, and read-only digital devices. Audio-visual disc player (DVD-ROM) and readable and writable digital video disc player (DVD-RW), flash memory and other non-volatile storage devices (nonvolatile solid-state storage device), tape • (taPe) and other similar devices combined with it. In some specific industries, such as PC manufacturers or hard disk manufacturers, it is often necessary to copy large pieces of data into one or more large storage units. Therefore, it is important that a copying machine that can stably and quickly copy large amounts of data to one or more large storage bodies (such as hard disks, flash memories, etc.). U.S. Patent No. 5,777,811 discloses a digital data reproduction system which describes a standard computer structure in a textbook and is now widely used in devices such as personal computers. Take this as an example to illustrate the negative impact of standard computer architecture on replication equipment. The main reason is to send the data of the system to the main memory (usually random access memory (RAM)) ^ and then write the data to another storage element. This kind of data transmission method is reliable 'but the speed of transmission will be fetched by the central processor, read and write: the difference between the text and the interference, but also the general random access memory: 5 at the same time only Or write restrictions have an impact; let alone memory _ _ selection will also affect the speed of transmission, and the results of the resident memory system • must match the structure of the selected computer, usually unable to meet the demand. In order to have a large amount of main memory, the computing machine currently selects dynamic memory, and this memory requires a first-in, first-out repetitive charging action and the 10-shirt rang a continuous data transmission bandwidth. Furthermore, the data is transferred from the main memory - when the target device is used, it is generally necessary for each target device to transmit once. This is a significant reduction in the speed of data transfer, especially for such mass-produced devices. U.S. Patent No. 6,131,141 discloses a hard disk drive duPlicat(R), which can be connected to a computer as an interface for operating the copy machine. The most important feature of the patent is that the data of the source storage component is directly transmitted to the target storage component by means of the _ control means, and the data transmission process is not temporarily stored in any buffer, thereby achieving high-speed data transmission. The function. Although this patent improved the related issues of 2〇 5,777,811, due to the lack of any buffer of data, the source and target could not absorb the dynamic data transmission flow changes, and all storage devices have similar problems. Although the average transfer speed of the same storage device is about the same, the instantaneous speed often changes. Even the same storage device does not guarantee the same transfer speed at the same time. 5 1303379 Because each transmission must wait for the slowest device, the speed of the transmission still has its limits. At the same time, in order to strengthen the thrust of the data, due to the increase of the destination device, we need to strengthen the signal strength of the source device, so as to prevent the number of the device from absorbing too much due to the target device, we will not be able to remove the original switch. It is possible to add a circuit that enhances the thrust, but the result of increasing the thrust often results in additional delay. As a result, the time it takes to transfer each piece of material is often greater than the normal time. U.S. Patent No. 6,931,459 also discloses a copying machine, mainly 10 15 , using a first in first out (Flrst In First 0, FIF) memory as a buffer for data transmission. The patent also provides a function of squatting the ice, recognizing an external poor source (4) and deleting the data ship (4). The external # material source is directly connected to the multiplexer, such a gentleman 槿 two 亜.
