Bus is a collection of lines connecting the above three components.<\/span> Buses can be analogized as a public road in front of our house we can pass if the neighbors were heading home, office, etc.<\/span> The difference is, in a general way at any given time there can be a lot of people or vehicles to pass through.<\/span> while for the bus, at one time there can be only one state (binary) for each track.<\/span> In other words, there are many components connected to the bus, but only a component that will fill the bus at a time.<\/span><\/p>\n

The bus in the computer system is divided into 3 groups, let us consider the third bus to work:<\/span>
\n a.<\/span> The data bus carries information to and from the processor element.<\/span> The data bus carries instructions dimabil of memory, input data from input devices, data is stored into the memory, and outputs the data into the output device.<\/span><\/p>\n

Data bus (data bus), which is used for the passage of data to and from each component in the data atas.Bus have a certain size, for example 8, 16, or 32 lanes.<\/span> This measure should not be the same as the size of the data in each memory location.<\/span> For example, if the memory size is 8 bits, then the 32-bit data bus will be able to move 4 the data (write \/ read four memory locations) at once.<\/span> Data bus width is usually used as a classification microprocessor.<\/span> Eg microprocessor 8 bit, 16 bit, or 32-bit, meaning she has a data bus width of 8, 16 or 32.<\/span><\/p>\n

Microprocessor data bus showed the ability to distribute a number of data at once.<\/span> Mikroposesor 8 bits or 1 byte, the hardware consists of 8 buses (D7MSB … D0LSB).<\/span> The data can be distributed simultaneously started (00000000 s \/ d 11111111) (B) or (00 s \/ d FF) (H).<\/span><\/p>\n

b.<\/span> Address bus is used to establish where did the data or where it comes from the data, this Bus pick a location in memory or a register tool open ended question – output I \/ O.<\/span><\/p>\n

Bus address (address bus), which is used by the microprocessor to send address information memory or I \/ O port to be contacted by him.<\/span> Address bus size determines how much memory there is, for example, the size of the 16-bit address bus (16 address lines) will be able to put address 216 or 65536 (64 kb) memory location.<\/span> Note the direction of the arrow to and from the bus address in Figure 2.7.<\/span>
\n Ideal microprocessor will have unlimited internal memory, but the real conditions that exist for storing data and programs need to be limited in number.<\/span> As a result, the microprocessor must be able to reach the external memory (external memory) to store data (read) and take back (write).<\/span> Communications between the microprocessor to the external memory is done through a “bus address”.<\/span><\/p>\n

c.<\/span> The bus controller is used to control the sequence and nature of the ongoing operations.<\/span> Bus controllers specifically indicating the type of operation such as “read data from memory to the processor, input device to read from or write to the instrument processor output of the processor, in addition, interrupt, direct memory access and other control functions carried by the bus line controller to implement the scheduling and penyerempakan incident.<\/span><\/p>\n

Bus control (control bus), which contains the lines for the purpose of sending control signals between components, for example, a signal indicating the cue to read, or write, election or port memory, interruptions, etc..<\/span> These signals are then determine what action should be carried out by each component.<\/span> Bus controller provides four functions, namely:<\/span>
\n a) memory Menyerempakan<\/span>
\n b) the input-output Penyerempakan<\/span>
\n c) Scheduling CPU \/ MPU – interrupt and DMA<\/span>
\n d) Maid, such as heartbeat and replace \/ delete (reset)<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
