Problems solved by technology

However, at present, memory cards made of flash memory have become indispensable products for the general public due to digital cameras, personal digital assistants (PDAs), mobile phones, etc., and the sales volume and types of memory cards are also increasing. The more memory cards use Universal Serial Bus (USB) or Integrated Drive Electronics Interface (IDE) as the transmission interface, the transfer rate of Universal Serial Bus (USB) and Integrated Drive Electronics Interface (IDE) Only 480Mb / s and 160MB / s, the transfer rate cannot keep up with the read and write speed of the memory card, so that the memory card will be blocked by the Universal Serial Bus (USB) or the integrated drive electronics on the host side (Host). Interface (IDE) is limited, and cannot achieve its own best state

Abstract

The invention is a card reader with the PCI Express. The card reader has the microcontroller which is connected with the PCI Express interface and the memory card interface; it also has the memory card interface, the PCI Express interface. When the card reader is connected to the PCI Express by the PCI Express interface, the host computer would memory the data in the memory card. The access rate can meet the speed provide by the PCI Express. So the card reader can reach the best transferring speed.

Description

technical field [0001] The present invention relates to a card reader with a high-speed peripheral component interconnection bus (PCI Express), especially a card reader using the high-speed peripheral component interconnection bus (PCI Express) as a transmission interface. Background technique [0002] Today's computer technology is growing at an ever-changing speed, and the development trend of its computers is also moving towards the direction of powerful computing functions and fast speeds, and because the clock pulse of the current central processing unit (CPU) is too fast, the transmission speed of other peripheral devices is basically It cannot keep up with the processing speed of the central processing unit. Therefore, even if the performance of the central processing unit continues to improve, there will not be much improvement. This is because the performance of the computer depends on the entire system, and the entire computer architecture must be improved. , in or...
