coded instruction 中文意思是什麼
-
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。 -
Assembler : a progamming language in which one mnemonic source statement is coded for each machine ? level instruction
匯編語言:一種編程語言，每一條助記符源語句都對應一條機器指令。 -
3 ) the instruction - level parallel calculation of streamlines on 3d curvilinear grids has been implemented firstly by using the streaming simd extensions ( sse ), which are a set of extensions of the intel pentium hi / 4 processor. compared with the conventional algorithm, sse - based algorithm coded by vector class library enhances performance about 55 %, and coded by inlined - assembly is about 75 %
） pentium （ pentium4 ）處理器的流simd擴展（ sse ） ，首次實現了3d曲線網格流線計算的指令級并行，與傳統演算法相比，向量類庫編碼實現的sse演算法將性能提高了55左右，嵌入匯編實現提高了75左右。
