A dual-core processor has two equally functional processor cores on one processor based on a single semiconductor, which is to integrate two physical processor cores into one core. In fact, the dual-core architecture is not a new technology. Until then, the dual-core processor has been the patent of the server. Now it is gradually facing ordinary users. In general, although the performance of dual-core processors has been improved compared with single-core processors, considering that most of the current applications, such as Office applications, games, video playback, and other applications are single-threaded, For most users, choosing a single-core processor is still the best choice. For users of professional video, 3D animation and 2D image processing, it is necessary to consider the dual-core system. CWDM - Coarse Wavelength Division Multiplex
CCWDM is Compact CWDM (Compact Coarse Wavelength Division Multiplexing), a wavelength division multiplexing technology based on TFF (Thin Film Filter). It works in the same way as CWDM modules, except that CCWDM uses free space technology. , compared with the common CWDM optical fiber cascading method , the CCWDM package size is greatly reduced compared with CWDM modules, and the insertion loss is lower and the consistency is better; it can replace CWDM Products are used in telecommunications, enterprise networks, PON networks, cable television and other fields. The lower insertion loss enables the CCWDM module to have lower signal attenuation during use, thereby reducing the power requirements of the signal transmitter.
For the CWDM module, limited by the minimum bending radius of the optical fiber line, the size of the packaging box cannot be made too small, resulting in most of the space in the box being idle. The adjacent channels of CCWDM use parallel beams to cascade in free space instead of optical fibers. Without the optical fiber used for cascading, the size of the CCWDM packaging box can be greatly reduced. For example, the size of the common standard 4CH CWDM is 80×60×12 mm, and the size of the CCWDM module of Yiyuantong is 50×27×7.7mm, which is only 1/4 of the standard CWDM package size. Can be widely used in high-density environments.

Before 2005, the main frequency has been the focus of the two major processor giants Intel and AMD. Moreover, the processor clock speed has also reached one peak after another with the promotion of Intel and AMD. At the same time when the processor clock speed is increased, it has also been found that in the current situation, the increase in the clock frequency alone cannot provide overall system performance. The improvement brought about by the obvious changes, along with the high frequency also brought huge heat to the processor, even more unfavorable is the Intel and AMD two processors in the frequency increase has been somewhat powerless. In this case, both Intel and AMD will invariably invest in the multi-core development direction, and develop existing products into theoretically more powerful multi-core processor systems without large-scale development.
