Computer data encryption the card PCIJMC2000 using data encryption and decryption of DSP and FPGA FPGA in curing block cipher algorithm the DSP running software encryption algorithm . PCIJMC2000 provide data processing speed of 10 ~ 20Mbit / s , using a combination of hardware and software encryption method can facilitate the achievement of the upgrade of the encryption algorithm , and the encryption code more secure and reliable . The topics focus is circuit implementation PCIJMC2000 . DSP has a highly parallel architecture dedicated hardware logic , and many specialized instructions , can achieve fast encryption algorithm , DSP dual access the RAM (DARAM) and the Host Parallel Interface (HPI) data the PCI transmission and DSP processing can be achieved at the same time , the other using the depth buffer , so spent the host interrupt time is almost negligible , and so based the the DSP computer data encryption card PCIJMC2000 get a higher processing speed . Detailed demonstration of the system design of the PCIJMC2000 discusses modules function with PCIJMC2000 hardware circuit design , PCB design , software design and module debugging to complete PCIJMC2000 card hardware trial . In addition, further studies of the thesis of the project is explained .
