4 Organisasi Sistem Komputer

5 Organisasi Sistem Komputer
Application (Netscape) Operating 20210 Compiler System (Windows 98) Software Assembler Instruction Set Architecture Hardware Processor Memory I/O system Datapath & Control Digital Design Circuit Design transistors Koordinasi dari berbagai tingkat abstraksi

6 Tingkat-tingkat Abstraksi Organisasi Komputer
Application S/W MS Word  computer as electronic type-writer MS Excel  computer as electronic calculator System S/W Compilers  computer as translator (source to executable program) Operating Systems  computer as machine that executes programs, stores files, prints content of files to printers, communicate with other computers Instruction Set What basic operations can be carried out What, where, and how data can be stored & retrieved in/from memory How can data be exchanged to the outside “world” Computer H/W The 5 components: Datapath, Control, Memory, Input, Output

7 Tingkat-tingkat Bahasa Pemrograman
C = A * B; High Level Language Program (e.g., C) 20210 Compiler lds r1, 0x100 lds r2, 0x102 add r1, r2 sts 0x104, r1 Assembly Language Program (e.g.,AVR) Assembler Machine Language Program (AVR) Machine Interpretation Control Signal Specification

8 Organisasi Bahasa Pemrograman Java
Java Language byte code Java Virtual Machine JVM dapat langsung berhubungan dgn h/w Operating System Computer H/W

9 5 Komponen Utama Komputer
Processor (active) Computer Control (“brain”) Datapath (“brawn”) Memory (passive) (where programs, data live when running) Devices Input Output Keyboard, Mouse Display, Printer Disk (where not running) That is, any computer, no matter how primitive or advance, can be divided into five parts: 1. The input devices bring the data from the outside world into the computer. 2. These data are kept in the computer’s memory until ... 3. The datapath request and process them. 4. The operation of the datapath is controlled by the computer’s controller. All the work done by the computer will NOT do us any good unless we can get the data back to the outside world. 5. Getting the data back to the outside world is the job of the output devices. The most COMMON way to connect these 5 components together is to use a network of busses.

17 Tren Teknologi

18 Tren Teknologi: Kapasitas Mikroprosesor
Alpha 21264: 15 million Pentium Pro: 5.5 million PowerPC 620: 6.9 million Alpha 21164: 9.3 million Sparc Ultra: 5.2 million Moore’s Law 2X transistors/Chip Every 1.5 years Called “Moore’s Law”

19 Tren Teknologi: Kinerja Prosesor
1.54X/yr Processor performance increase/year, mistakenly referred to as Moore’s Law (transistors/chip)

20 Tren Teknologi: Kapasitas Memori (1 Chip DRAM)
year size(Megabit) 1986 1 1989 4 Now 1.4X/yr, or doubling every 2 years 4000X since 1980

21 Teknologi Komputer  Perubahan Dramatis
