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

三種16位整數(shù)運(yùn)算器的ALU設(shè)計(jì)方法，調(diào)用庫函數(shù)74181（4位ALU），組成串行16位運(yùn)算器。(用74181的正邏輯) B．調(diào)用庫函數(shù)74181和74182，組成提前進(jìn)位16位運(yùn)算器。(用74181的正邏輯) 注意：調(diào)74181庫設(shè)計(jì)，加進(jìn)位是“0”有效，減借位是“1”有效，所以最高位進(jìn)位或借位標(biāo)志寄存器要統(tǒng)一調(diào)整到高有效 C．用always @，case方式描述16位運(yùn)算器。
