Abstract

Communication is the process of sending information from one place to another, howthe delivery of information have their own modes and methods. With the computerthe way of sending information is also adjusted to the principles and workings of thecomputer.But computers can not perform data transmission without a tool that can make it ableto carry out the process of data transfer. One of these tools is the IC is an IC 8251AUSART (Universal Synchronous / Asynchronous Receiver Transmitter) is IC that isused to implement the information delivery process using serial synchronous /asynchronous.The advantage of using this chip is its ability to be programmed (programmable) inaccordance with the procedures contained in IC programming this 8251A.

Abstract

In this writing assignment is discussed about the system cache memory on the microcomputer system with memoi cache on the microprocessor that is useful to speed up computer performance. type of cache used is of type M-way set-associative caches on microprocessors is a Two-way associative cache. Suitable for this type of cache operations multiprosesing because relatively inexpensive and simple. Microprocessor has a separate cache memory data cache, for data and code for instruction cache.  The cache memory itself is a technique to improve overall system performance by combining a small random access memory with a large conventional RAM (which is slower but cheaper), so that would be obtained by high-speed memory that a large capacity with relatively cheap price.

Abstract

In this thesis, we presented the design of measuring devices, which may be used to measure the effective voltage value of an electrical signal.operation of this measuring instrument used for measuring the effective price of the wavesthat shaped not sequentially, either periodically or non periodic.Designrestricted to the use of measurement of stress waves within the audio frequency region.The main circuit consists of voltage sensor, which at the same time as devidervoltage, the effective price of a modifier of voltage (current) direction, and the last is a digital voltmeter. The output from the sensor circuit signal voltage is still a form similar to the original signal is measured, but the amplitude is different, tailored to local measurements. Modifiers effective price will count valueto floweffective unidirectional signal output from the sensor circuit. The output of this converter circuit becomes the input of digital voltmeter, which is then displayed by the viewer seven sections (seven segment).
