Hyper Data Transfer for BioStar 2

The available memory bandwidth and increasing CPU performance outpace that of I/O devices. As a result, handling the I/O operations perfectly is the key point for designing a system architecture. For this reason, the BioStar 2 server adapted an asynchronous system architecture for handling network I/O operations. Before taking a deep look into the asynchronous system architecture, let’s understand the synchronous system architecture first.

New Image Compression Technology of SFM5500 Series

The SFM5500 series overcame this problem and have been equipped with the new technology to compress fingerprint images and quickly send high quality images via a low bandwidth network environment. When compressing, the quality degradation is minimized (Figure 2), but the data size is lowered by 90%, reducing the time it takes to be sent by 90%, as well. Moreover, you can set the system to compress images in different levels, enabling you to appropriately adjust the transfer speed and the image quality according to its use.
