The addressing mode of assembly language instruction set of 80C51 MCU is redefined. The addressing mode is classified according to two standards separately. The addressing mode is the method decrypting operand address in the instruction, or finding the next instruction address. The mode to find the operand address includes direct addressing, register addressing, register indirect addressing and base address plus index indirect addressing. The mode to find the next instruction address includes sequential addressing, base address plus index indirect addressing and relative addressing.

We have assembled an image processing system for use with our high resolution STEM for the particular purpose of working with low dose images of biological specimens. The system is quite flexible, however, and can be used for a wide variety of images.The original images are stored on magnetic tape at the microscope using the digitized signals from the detectors. For low dose imaging, these are “first scan” exposures using an automatic montage system. One Nova minicomputer and one tape drive are dedicated to this task.The principal component of the image analysis system is a Lexidata 3400 frame store memory. This memory is arranged in a 640 x 512 x 16 bit configuration. Images are displayed simultaneously on two high resolution monitors, one color and one black and white. Interaction with the memory is obtained using a Nova 4 (32K) computer and a trackball and switch unit provided by Lexidata.The language used is BASIC and uses a variety of assembly language Calls, some provided by Lexidata, but the majority written by students (D. Kopf and N. Townes).

This study was conducted based on the facts about the lack of maximal outcomes of learning English in almost all levels of education, especially in vocational school. Although English has been studied for many years, but the majority of students can not master English well, especially speaking. Many factors cause this phenomenon, and all parties should concern to work together to formulatebetter system and process of English learning at vocational school.The research was conducted at SMK Negeri 1 Pacitan, by taking the students of class XII as subjects research. The sample of this research consists of 94 students of Business Travel and Tourism,Network Computer Engineering, and Engineering Software classes. This research uses descriptive qualitative method. It is used to describe the students’ speaking competence, particularlyin presenting final task report. This research also identifies the internal and external functions to formulate a strategy to improve the students’s speaking competence. The results showed that based on the analysis of English speaking competency of SMK Negeri 1 Pacitan students, it can be concluded as follows: a). Based on the students absorption analysis of presenting final project report, shows that English competency level of students is in the category of “pretty”, with evidence of the studentsvalue average in presenting final project report is more than the passing grade value (7.50),it is 79.5. While the number of student, who passed the presentation test,is 66 students.So it can be obtained the percentage level of mastery learning students on the presentation test of final report is only 70.21%, and it is categorized “less”, because the percentage of students who passed this exam is still under 75%. b). While the analysis of the questionnaire can be scribed that the average overall score of 3.44 speaking competence components are categorized “pretty”, and it can be concluded that the level of competence of English speaking students generally categorized “enough”. Based on the level ofstudents’ English speaking competence , it can be formulated the strategies to increase its competence. They are: a). Maximizing the use of English as a language instruction and reducing the use of Indonesian, especially in the learning process, to improve English language competency, so that students can have the ability to explain the sequence of events and the students can pass the exam well. b). Having more English presentation activitiesin other topics to encourage the students’ bravery and self-confidence in speaking English, so that students have good Englishcompetence as preparation to getjobs or to continue their study at university.c). Having more exercise of using body language to improve the mastery of speech, and smooth attitude, so that students have good English competence,and they are able to compete in the global world in obtaining employment. d). And maximizing the use of school’s facilities by using various methods of learning, and focusing on the students’ center method to improve the studentsEnglish competency so that they are able to compete for educational scholarships in this country and abroad.
