汇编艺术（国外英文资料） Assembly language is an undigested, raw computer language, and readers can work hard to find out The rules of the application are applied to the maximum efficiency. Below, I offer a few superficial and simple contributions to my personal experience Their discussion. To write a good program, you should first remember the Clock pulse (Clock) and the length of instruction of the 8088 command, and the general assembly language In the manual, the data is detailed in the instructions. If the work is good, it will be the first. In this section, the details that the average programmer can easily ignore, all of them are from the ones Ive seen Its taken from the program. It doesnt seem to be a big deal, but the efficiency of the program is affected by these little places, right Big. More importantly, anyone who has the habit of doing nothing, doing nothing, I swear, is The individual will not have any great achievement! I recently found the clock value for Effective Address (EA), which I dont think is necessary. In principle, The register is the variable, the indirect addressing is 5 clocks, and the direct addressing is 6; If you use two sets of variables, There are seven to nine, and three groups of 11 or 12. In order to facilitate the narrative, the following is the T table clock pulse; B table characters. Among them The clock pulse T = 1 / oscillation frequency Avoid wasting speed and space The efficiency of assembly language is built on the application of the instruction, and if the following instructions are not fully understood, the following instructions are compiled The advantages of language are difficult to exert. 1, CALL ABCD RET This is a way of writing, without an intentional result, sharing 4B, 23T + 20T, exactly the same function, such as: JMP ABCD or JMP SHORT ABCD Its just 2 minus 3B, 15T. In addition, the CALL XXXX above is the format of the CALL subroutine, in the intuitive sense, with JMP XXXX All different. It is an unforgivable mistake for t
