The DHRY program performs the dhrystone benchmarks on the 8051. Dhrystone is a general-performance benchmark test originally developed by Reinhold Weicker in 1984. This benchmark is used to measure and compare the performance of different computers or, in this case, the efficiency of the code generated for the same computer by different compilers. The test reports general performance in dhrystones per second. Like most benchmark programs, dhrystone consists of standard code and concentrates on string handling. It uses no floating-point operations. It is heavily influenced by hardware and software design, compiler and linker options, code optimizing, cache memory, wait states, and integer data types. The DHRY program is available in different targets: Simulator: Large Model: DHRY example in LARGE model for Simulation Philips 80C51MX: DHRY example in LARGE model for the Philips 80C51MC

三种16位整数运算器的ALU设计方法,调用库函数74181(4位ALU),组成串行16位运算器。(用74181的正逻辑) B.调用库函数74181和74182,组成提前进位16位运算器。(用74181的正逻辑) 注意:调74181库设计,加进位是“0”有效,减借位是“1”有效,所以最高位进位或借位标志寄存器要统一调整到高有效 C.用always @,case方式描述16位运算器。
