data block length 中文意思是什麼
data block length
解釋
數據塊長度-
You can choose different encipher algorithms according to requirement. aes is a symmetric block cipher that can process data blocks of 128 bits, using cipher keys with lengths of 128, 192and 256 bits. because the length of block and key has been expanded, security has been enhanced
Aes （ advancedencryptionstandard ）是fip （ federalinformationprocessingstandardspublication ）在2001年6月發布的草案，它是分組加密演算法，消息分組為128bit ，有三種密鑰長度128bit 、 192bit 、 256bit ，由於分組長度和密鑰長度加長使得安全性大大的提高，它有望成為21世紀的加密標準。 -
The risc mcu core is based on harvard architecture with 14 - bit instruction length and 8 - bit data length and two - level instruction pipeline the performance of the risc mcu has been improved by replacing micro - program with direct logic block
設計的riscmcu採用14位字長指令總線和8位字長數據總線分離的harvard結構和二級指令流水設計，並使用硬布線邏輯代替微程序控制，加快了微控制器的速度，提高了指令執行效率。 -
The core is based on harvard architecture with 16 - bit instruction length and 8 - bit data length. the performance of mcu has been improved greatly by introducing single - clock - cycle instructions, setting multiple high - speed working registers and replacing micro - program with direct logic block etc. to keep the mcu core reusable and transplantable, the whole mcu core has been coded for synthesis in verilog hdl
該mcu核採用哈佛結構、 16位指令字長和8位數據字長，通過設計單周期指令、在內部設置多個快速寄存器及採用硬布線邏輯代替微程序控制的方法，加快了微處理器的速度，提高了指令的執行效率。 -
