携带向前看加法器

The use of FPGAs for cryptographic applications is highly attractive for a variety of reasons but at the same time there are many open issues related to the general security of FPGAs. This contribution attempts to provide a state-of-the-art description of this topic. First, the advantages of reconfigurable hardware for cryptographic applications are discussed from a systems perspective. Second, potential security problems of FPGAs are described in detail, followed by a proposal of a some countermeasure. Third, a list of open research problems is provided. Even though there have been many contributions dealing with the algorithmic aspects of cryptographic schemes implemented on FPGAs, this contribution appears to be the first comprehensive treatment of system and security aspects.

I2C verilog code I2C僅使用兩個雙向開漏線，串列資料線（SDA）和串列時鐘線（SCL），上拉了電阻。使用的典型電壓是+5 V或+3.3 V（雖然其他電壓系統也是允許的）。 在I2C參考設計中，使用7位或10位（取決於所使用的裝置）位址空間。普通I2C匯流排速度為100 kbit / s的標準模式和10 kbit / s的低速模式，但任意低時脈速率也是允許的。 I2C的最新修訂可以承載更多的節點，並以更快的速度執行[b]。這些速度被更廣泛地使用在嵌入式系統中而不是PC上。I2C也有其他的特性，例如16位元尋址。(I2C verilog code I2C (Inter-Integrated Circuit))

用于FPGA的学习，大家值得借鉴，可以好好学习一下(this is for fpga and you can use this.)
