2) transcending evaluation
超越进化
3) carry-lookahead
超前进位
1.
Variable-sized blocks,complementary carry logic between blocks and multilevel carry-lookahead logic within blocks are used to achieve a high-performance adder.
该文提出了一种以两位加法器模块构成的静态进位跳跃加法器,通过对加法器尺寸的优化方块分配、方块之间的互补进位产生以及方块内部的多级超前进位逻辑3种方法获得快速静态进位跳跃加法器。
2.
A fast carry-skip adder is proposed based on variable-sized two-level block carry-lookahead logic.
提出了一种基于方块超前进位的快速进位跳跃加法器。
4) Carry lookahead
超前进位
1.
Take into account the chip s speed and area,the design is realized by a cascade of basic cell based on 4 bit CLA and 4 bit carry lookahead generator,so this circuit shows its compromised advantage of computation speed and chip area.
本文介绍了用原理图输入方法设计一款图象处理ASIC芯片中乘加单元的核心运算部件——32位超前进位加法器,出于速度(时延)和面积折衷优化考虑,它以四位超前进位加法器和四位超前进位产生器为基本设计单元级联而成,因此该电路具有速度和面积的折衷优势。
5) transcendental approach
超越的进路
