COMES OF ARCHITECTURE, PROGRAMMING AND DEVELOPMENT OF SYSTEMS WITH CHIPS (10)

AT THIS TIME OF READING MADE that bear would be good TOMASEIS ALL PAPER AND PENCIL E ye should A 4-bit microprocessor generates LIKE TO BE APPLIED IN TOYS IN THE 70. AT THAT TIME BUT THE GREAT SALT LAKE their order already existed was still in DIAPERS TECHNOLOGY MAINLY BY THE ABSENCE OF LARGE SCALE INTEGRATION. At that time was critical ELECTRONICS ELECTRONIC COMPONENT.
STEP IS DEFINED IN THE DESIGN CPU'S THE BIG BLOCKS
CIRCUIT encoding / decoding REGISTRATION INSTRUCTIONS INSTRUCTIONS. SEQUENCER CIRCUIT AND TIME BASIS. DIVISION OF INSTRUCTION IN SMALLER Microinstructions and generalized. THIS WAS KNOWN AS CIRCUIT CONTROL UNIT. EXITS AND ENTRANCES AND INCLUDING RULES ALL OTHER COMPONENTS OF THE PROVISION OF CIRCUITRY (INPUT / OUTPUT, PERIPHERALS, the different blocks of memory, PROGRAM, DATA MEMORY, MEMORY OF INTERIM RESULTS, INTERFACE CIRCUIT, INTERFACE CIRCUIT WITH LISTENING BY CPU INTERFACE CIRCUITS WITH INTERRUPTIONS, peripheral circuits, clock signals)
CIRCUIT arithmetic and logical operations. Adder / subtracter N BITS PARALLEL. SEMIACARREO BITS, BIT OF CARRY, OPERATIONS IN ADDITION TO TWO, PARITY, sign bit, floating point operations. INTERNAL RECORDS SET CPU TO PROVIDE EASIER ACCESS TO DATA AND NO NEED FOR ACCESS TO MEMORY.
STRUCTURE OF ALL BUS: BUS DATA BUS ADDRESS (Sometimes these are multiplexed, PROBLEMS WITH The inductances mutual induction and unworkable MAKING CERTAIN FREQUENCY CIRCUIT, AS ARE PROBLEMS WITH THE ELEMENTS and capacitance between CHIP PINS OF MAKING APPEAR LOW PASS FILTERS also limits the operating frequency, hence the need TO HAVE SOME REAL DEVICE SIMULATION / EMULATION CPU BEFORE STARTING YOUR REAL)
BUS DATA, CONTROL BUS, BUS PERIPHERAL ADDRESSES AND FROM OUTSIDE THE STRUCTURE OF BUSES BUSES TO INDUSTRIAL MATCHING.
INTERFACE CIRCUITS: ARE PRIOR TO THE PERIPHERAL AND ALLOW THE DIALOGUE WITH THEM. ARE BASICALLY THE PERIPHERAL MONITOR, KEYBOARD, AUDIO SYSTEMS, PRINTERS. MEMORY AND NOW ALL THAT IS INTRODUCED THROUGH THE USB styli (NOW IN 2010 HAVE ALLOWED THE STORAGE Of the greatest AMOUNTS OF MEMORY IN LINE WITH THE ACTUAL NEEDS TODAY WE ALL CONSUMERS AND USERS OF THE COMPUTER).
NOVEMBER 2010: We will introduce concepts related to the popularization of the BASED OPERATING SYSTEM FOR INDUSTRIAL FACILITIES IN THE JAVA and as the PC can become a JAVA MACHINE ENVIRONMENT, IN THIS WAY THE PC STOPS TO BE RAISED AS IF THE WINDOWS OPERATING SYSTEM THAT ARE MORE OR APPLE predominant RELATED WORK ENVIRONMENT OFFICE OR TREATMENT OF INFORMATION IN OFFICE. WE KNOW THAT THROUGH automata and poses important ADJUSTMENTS TO OPERATING SYSTEMS (in other words a "blanket or hood should be mounted over the operating system" and allows us to disguise PURSUANT TO THE KNOWLEDGE AND SKILLS THAT HAVE THE STAFF ARE SUPPOSED TO MIDDLE-AGED AND RELATIVELY SO poorly trained). SAY THAT PLC THROUGH LARGE QUANTITIES OF PERSONAL SERVICE AREAS AND LABORATORY OF LARGE AND MEDIUM COMPANIES TO WORK WITH THE MACHINES CAN NOT NECESSARILY HAVE TO UNDERSTAND THE ESSENCE OF YOUR DEVICES AND RESOURCES. The latter include the destruction of MICROPROCESSOR RESOURCES AND LAYING AND FIXING OF LARGE AMOUNTS OF MEMORY TO SUPPORT SUCH ADJUSTMENTS TO THE OPERATING SYSTEM. IN ANY WAY THE WAY TO WORK IN JAVA ENVIRONMENT ASSUMED THESE EXTRA SIMPLIFIED MACHINE SETTINGS. THAT IS THE JAVA ENVIRONMENT AND PRESENTATION OF THE PC AS A JAVA VIRTUAL MACHINE APPROACH TO IMPLY THAT THIS IS THE PC AS A MACHINE THAT WILL WORK IN INDUSTRIAL ENVIRONMENT (UNDERSTANDING LEVELS OF NOISE, SATURATED ELECTROSTATIC ENVIRONMENT, remoteness of certain DEVICES ETC. .. AND ELECTRONIC MACHINERY AND UNDERSTAND THAT LITTLE REASON FOR THIS VERY DIFFICULT TO SET UP ON AUTOMATION SOLUTIONS Standardized). THIS LAST SENTENCE I am talking about JAVA ENVIRONMENT THAT IS VALID FOR RAISING THE AUTOMATION SOLUTIONS DEVELOPED THROUGH TODAY MICROCOMPUTERS WITH WASHING MACHINE SYSTEMS, TIME, AND SYSTEMS BY EXAMPLE OF CROSSING TRAFFIC CONTROL).
JAVA VIRTUAL MACHINE OPEN PROGRAMMING CONCEPTS RELATED TO ORIENTED PROGRAMMING ENVIRONMENT AND IS RELATED FORMS OF VISUAL BASIC PROGRAMMING LANGUAGES AND OBJECT ORIENTED PROGRAMMING AS THE EVOLUTION OF PASCAL LANGUAGE C (I THINK THAT DEVELOPED WITH THE UNIX OPERATING SYSTEM UNIFICATION ATTEMPT ON THE YEARS OPERATING SYSTEMS 80) AND THE C SUBSEQUENT DEVELOPMENTS IN TURBO CY IN TURBO C + +. TURBO C + + OBEY TO OBJECT ORIENTED PROGRAMMING AND DEVELOPMENT AND WELL MADE POSSIBILITIES IN THE PROGRAM MAY BE PUT DIRECTLY SUBROUTINES AND VERY CLOSE TO OWN RATHER ASSEMBLY LANGUAGE OR MACHINE CODE. REMEMBER THAT ON THE 90 FOR THE LARGE AMOUNT AT THE TIME OF WRITING AND CODE FOR 80286 and 80386 PREVAILED FOR THE GREAT TO THE DIFFICULTY OF THE LOW-LEVEL PROGRAMMING IN PREPARATION FOR THE GREAT NEED FOR IT TO THAT PROGRAMMERS THE DESIGN OF CHIPS MANDARA OWN THE "SOFTWARE" HARDWARE ON YOUR OWN. This requires TWO CONSIDERATIONS CAN BE EFFICIENT COMPILERS with very few lines of code generate large amounts HIGH LEVEL ASSEMBLER CODE AND THE CODE NUMBER OF FAT would not be too exaggerated.
