1. Overview Xilinx FPGAs starting from the 7 series have on-chip Advanced Encryption Standard (AES) decryption logic, providing a high level of design security. Encrypted Xilinx FPGA designs cannot be copied or reverse-engineered for other FPGAs.The Xilinx FPGA responsible for encryption uses an AES system consisting of software-based bitstream encryption and on-chip bitstream decryption, with … Read more
In the previous article, Xiaozhao introduced CPU and GPU. Today, I will continue to introduce two other main characters in the field of computing chips—ASIC and FPGA.█ ASIC (Application Specific Integrated Circuit) As mentioned earlier, GPUs have strong parallel computing capabilities, but they also have disadvantages, such as high power consumption, large size, and high … Read more
Fixed-point decimal division is much more complex than addition and multiplication, but the basic idea of the algorithm is still quite simple. Similar to integer division, the core idea of the algorithm is to convert the division operation into shift and subtraction operations. From a practical implementation perspective, there are generally two methods: One is … Read more
