Abstract

In accordance with the present invention, a method and a system for increasing scanning speed are provided. The method comprises steps of determining a transmission rate of a transit interface, scanning an original to generate an image data, and adjusting a cycle time of the image data to change a data generated rate responsive to the transmission rate of the transit interface. The key aspect of the present invention is by adjusting the cycle time of a state machine to change the data generated rate corresponding to the transmission rate of the transit interface. Therefore, in response to the transmission rate of the transit interface, the cycle time of the state machine is adjusted to produce the data at a rate that prevents the smearing process. Thus, incorporated with the present invention, the possibility of memory buffer full is reduced leading to the reduction in the time wasting on start-stop processes and therefore the overall scanning speed is increased without requiring the increase in size of a memory buffer.

V. Description of the invention (1)

In the field of invention of 5 ~ 1, the win J is about a method for improving the scanning speed. This is only 9 ^ • month is a kind of cool and descriptive system through the transmission interface. State machine cycles to change data Fans: Judgment, t method and scanning system. 3, 3 scan speed / 5 2 Background of the invention: Scanning pand cabled computer. The communication protocol capture rate is related to the fact that there is no need to store the receiving speed for transmission. However, the scanning operation efficiency is related to the transmission of data because these digits can be sent and stored. The ideal host can receive the data sent by the memory buffer. different. If the fastest speed of the scanner is related to the transmission rate of the data, the digital data representing the content of the original is widely distributed through the input / output line (j / 〇 host side, for example, the data is transmitted by the scanner side). The transmission rate is the same as that used by the scanner and the host. The data generated and received at the host is at the same rate. In this way, the scan of the system buffer (memory buffer) is cumulative. However, the data generated The speed and the transmission rate of the host are usually greater than the rate of data generation. Scanning generates data without problems of data loss. When the transmission rate of the host is usually greater than the rate of transmission of the host and the rate of data is lower than the rate of data generation, problems often occur.

546945 V. Description of the invention (2) (Scanning speed is defined as the accumulation to the host is filled in the memory buffer, which causes the fixed point to be driven by the motor again when the buffer is full. After starting the scan mode, when the accumulation starts scanning The tracing procedure is completed because it is not speed. In the false buffer area, the image data of the data is completely damaged. The scan mode is completely started. The scan mode is a few steps back. The group has just started the buffer scanning process. This repeats, in addition to the optical resolution, the scanning speed, another factor that determines the function of the scanner. When scanning starts, the scanner will scan the scanned image data back. If the transmission rate is slow, the image data may gradually scan only a part of the original, and then accumulate the data: it is full. To avoid losing the memory buffer, the scanning process is usually paused first. Then, the transfer is complete or there is room for another 'data program'. In other words, when the buffer is full, = will pause the scan first, and then take a few steps back to: ^ I Ϊ Because of mechanical inertia, the mouth will be shaken again, which will affect the scan quality. == 2. Scanning module is re-opened = ran to start / pause # $ 二 k 1 1. Sequentially lengthen the scanning time c Move the scanning module backwards | Or suspend the scanning module and = door = start The process of moving,). This program also looks at the sequence (start ~ st〇p problem, but it is a waste of time, time, and time, and I do n’t know how to fill it or the buffer is full.) Expected various transfer speeds

In other words, when a high-resolution scan is performed, the ::: scheme is more complicated. In addition, it's like a shellfish, so we can produce a viable method. The capacity of the punching area of the knife is not that the scanner has a fast scanning time. It can also reduce the speed and speed of the scan. + A comment on the buffer capacity of the original document can reduce / s exhibition-a kind of time that is not wasted by adding hips to the fT sequence, thereby reducing the start of the scanning system. It is very urgent. 3 The method of knowing the trace speed and 3 The purpose and summary of the invention: The transfer rate of the yield. In view of the many shortcomings in the background of the invention described above, the invention provides a scanning method and scanning system method and scanning system. The key tf of the present invention is to increase the scanning speed to adjust the number of state machine cycles. The reason for the corresponding transmission interface: dagger. The present invention can change the data generation according to the number of speed periods generated by the transmission medium. Speed: the opportunity to adjust the rate of transmission, adjust the state sequence, and let the overall scan be reopened and "limited to the transmission interface"

4 Detailed description of the invention In addition to the detailed description of some embodiments of the present invention, the present invention can also be broad. However, except for the scope of the present invention, the scope of the present invention is not limited, which is also: the implementation of the embodiment, and the silly patents shall prevail. A state machine is a series of processes that logically _ connect to another state ^ and pass through a state. Take the femoral scanner as an example, the second scanner; two = internally controlled state. For example, every fixed period is m fixed clock, with a fixed number of machine cycles. For example, the scanning method is widely known in the art. Autumn and summer are the different transmission interfaces that should be used before: the transmission rate produces an optimization of the profile speed. In other words, when 2 is different and the transmission rate of the interface is faster, or when the generation rate of the two necks is faster than the transmission makes the buffer fill up, it is impossible to avoid generating a large amount of data in $ j and it cannot be reduced. Wasted during the start / pause program. In operation, when the number of state machine cycles is small, 7, the time of Wang Xu i. It becomes slower when T, which will generate more start / pause procedures, encounters a slower transmission rate. When the state machine cycle number% is the overall scanning speed rate at this time, it will make the transmission interface even faster: 4 ′ encounters a faster transmission speed and reduces the overall scanning speed. Therefore, the month and month turn time (i d 1 e t i m e) is optimized. Looking at the shortcomings of the prior art, == may reach the maximum of the scanning speed, and use the state machine cycle number adjustment to provide a way to change the generation rate of data according to the transmission medium ...

For example, the high state machine is changed to the interface. It is passed "that is, as a clock, the invention is achieved by buffer filling." The set of multiple state machine cycle groups ": by: the number of transmission rates.

Conversely, when IEEE 1 3 94 with fast transmission speed can reduce the number of state machine cycles, the cycle contains 10 clocks, and it can be changed to include the idle time of the transmission interface, as shown in Figure B. Therefore, the time between the machine cycle and the transmission rate Balance, reducing the chance of image data / X, and reducing the time delay caused by starting the pause process to the optimization of the scanning speed. The invention also provides a method to improve the scanning speed. Refer to the flowchart of the invention. The inventor

That is, the scanning module scans the number of cycles of the original data, and the control Next, adjust the image to fill. The adjustment of the number of state machine cycles is based on the input loss: the transmission rate of the red zone, the number of high speeds. For example, the transmission interface has three full speeds. Low-speed). Once the value is determined, the low-speed (machine cycle number (or cycle included in
