Microprocessor

A microprocessor incorporates most or all of the functions of a central processing unit (CPU) on a single integrated circuit (IC). The first microprocessors emerged in the early 1970s and were used for electronic calculators, using BCD arithmetics on 4-bit words. Other embedded uses of 4 and 8-bit microprocessors, such as terminals, printers, various kinds of automation etc, followed rather quickl

These interview questions test the knowledge of x86 Intel architecture and 8086 microprocessor specifically. What is a Microprocessor? - Microprocessor is a program-controlled device, which fetches the instructions from memory, decodes and executes the instructions. Most Micro Processor are single- chip devices.Give examples for 8 / 16 / 32 bit Microprocessor? - 8-bit Processor - 8085 / Z80 / 6800

Microprocessors or commonly known as the central processing unit (CPU). It is the brain of the computer where all programs of the computer system are process and manipulated. It is like a chip in a single Integrated Circuit (IC) which composed of many electronic components that deals with the IC.Early morning, when a man appeared and came to asks some questions about the microprocessors and the co

The CPU is the first thing that comes to mind when many people think about a computer's speed and performance. The CPU is the part of a computer in which arithmetic and logical operations are performed and instructions are decoded and executed. The CPU controls the operation of the computer. Early PCs used several chips to handle the task. Some functions are still handled by support chips, which a

Via Technologies, a struggling designer of core-logic sets and x86 central processing units, will reportedly utilize new process technology and introduce processors with two cores by the end of next year. While this will boost competitive position of Via’s chips, the company will still be unable to offer alternative for processors by Advanced Micro Devices [...]

Apple has finally done something with its cash, although spending a tiny part of it, after much speculation of what it would do: it has bought a boutique microprocessor design company called PA Semi. The price, not disclosed, but the story says around $278 million in cash.PA Semi, which is known for its design of sophisticated, low-power chips, could spell a new future for Apple's flagship

emu8086 is the emulator of 8086 (Intel and AMD compatible) microprocessor with integrated 8086 assembler and tutorials for beginners. The emulator runs programs like the real microprocessor in step-by-step mode. It shows registers, memory, stack, variables and flags. All memory values can be investigated and edited by a double click. The instructions can be executed in a regular forward direction and also in reverse direction.emu8086 can create a tiny operating system and write its binary code to a bootable floppy disk. This software package includes several virtual external devices: robot, stepper motor, led display, and traffic lights intersection. Virtually anyone with any programming experience can design animated virtual devices in assembly language or in any other programming languag

Microprocessor Emulator and Assembler is a 8086 microprocessor simulator.Assembler with Microprocessor Simulator 8086 is the perfect solution to debug short programs and to study assembly language programming as part of a computer science course.Emulator runs programs on a Virtual Machine, it emulates real hardware, such as screen, memory and input/output devices. 8086 instruction set is the ABC for all modern computing, it's the base of all microprocessors including Pentium and Athlon. 8086 is the computer DNA code.Though internal assembler is primitive compared to those developed by Borland and Microsoft, all Intel's instructions and even some MASM and TASM directives are supported.It's ideal for Computer Architecture study.Emu8086 combines an advanced source editor, assembler, disassemb

The "vocabulary" of instructions which any particular microprocessor chip possesses is specific to that model of chip. An Intel 80386, for example, uses a completely different set of binary codes than a Motorola 68020, for designating equivalent functions. Unfortunately, there are no standards in place for microprocessor instructions. This makes programming at the very lowest level very confusing and specialized. When a human programmer develops a set of instructions to directly tell a microprocessor how to do something (like automatically control the fuel injection rate to an engine), they're programming in the CPU's own "language." This language, which consists of the very same binary codes which the Control Unit inside the CPU chip decodes to perform tasks, is often referred to as

In Microprocessor more op-codes, few bit handling instructions. But in Micro controller: fewer op-codes, more bit handling Instructions, and also it is defined as a device that includes micro processor, memory, & input / output signal lines on a single chip. Share This

IBM claims to be launched the world's fastest chip for UNIX serversIBM just launched the dual-core 64-bit POWER6 processor running at 4.7 GHz, which doubles the speed of the previous generation POWER5 while using nearly the same amount of electricity to run and cool it.The POWER6 processor is a result of a five-year R&D period, is composed of 790 million transistors and is built using IBM’s 65nm process technology. IBM scientists targeted the way instructions are executed inside the chip to improve performance. For example, in the POWER6, the number of pipeline stages – the chunks of operations that must be completed in a single cycle of clock time – are kept static, but each stage is made faster, removing unnecessary work and doing more in parallel. As a result, execution time is reduced. Earlier this year, IBM hinted that its new POWER6 architecture may hit frequencies higher than 5 GHz. The POWER6 chip has a total cache size of 8 MB per chip – four times the POWER5 chip –

Ok, while browsing the local thrift stores for hackable electronics, I ran across this little guy in the keyring tray for 29 cents.   I couldn't pass this up. I remember all the good times I had with our first x86 computer... read more
