3、st important part?We take operate an abacus as the example computation together arithmetic topic. Example: 36 + 163156 - 16634. Now must carry on the operation, first needs an abacus, next is the paper and the pen. We the question which must calculate record, then first step calculates first 163156,
4、 with the result which 36 adds together records it on the paper, then the computation 16634, then subtracts it from the previous result, obtains the final result.Now, we use the monolithic integrated circuit to complete the above process, obviously, it first must have replaces the abacus to carry on
5、 the operation the part, this is the logic unit; Next, must have can play to the paper and the pen role component, namely can remember the primitive topic, the primary data and the intermediate result, but also must remember causes the monolithic function automatically to carry on each kind of order
6、 which the operation but establishes. This kind of component is called the memory. In addition, but also needs to have can replace the controller which the human affects, it can act according to the order which beforehand assigns to send out each kind of control signal, enables the entire computatio
7、n process one to carry on step by step. But the light has these three parts to be also insufficient, the primitive data and the order needs to input, the computation result must output, all needs according to in turn to carry on successively, sometimes also must wait for.Like on in example, when whe
8、n computation 163156, the numeral 36 cannot at the same time enter the logic unit. Therefore needs to establish on the monolithic integrated circuit according to the controller order carries on the movement the gate, when the logic unit needs, lets the recent data enter. Or, when the logic unit obta
9、ins the final output, again this result output, but the intermediate result cannot be casual slips away the monolithic integrated circuit. This kind to inputs, the output data carries on the certain management the gate the electric circuit to be called the mouth in the monolithic integrated circuit
10、(Port). In the monolithic integrated circuit, basically has three kind of information in to flow, a kind is a data, namely each kind of primary data (for example on in example 36, 163 and so on), intermediate result (for example 16634 obtained business 4, complement of a number 30 and so on), proced
11、ure (order set) and so on. This must pass the mouth by the external instrumentation to enter the monolithic integrated circuit, again deposits in the memory, in the operation treating processes, the data carries on the operation from the memory read-in logic unit, the operation intermediate result m
12、ust store in the memory, or finally passes through the access by the logic unit to output.The user wants each kind of order which the monolithic integrated circuit carries out (procedure) also by the data form by the memory to send in the controller, (decoding) becomes each kind of control signal af
13、ter controller , in order to carries out like adds, reduces, while, eliminates and so on function each kind of order. Therefore, this kind of information is called the control command, namely controls the logic unit by the controller one to carry on the operation and processing step by step, also co
14、ntrols the memory to read (takes out data) and writes (log data) and so on. The third kind of information is the address information, its function is tells the logic unit and the controller takes the order fetching in where according to, finally will deposit to any place, through which mouth input a
15、nd output information and so on.The memory divides into the read-only memory and the read-write memory two kinds, former depositing debugs the fixed routine and the constant, latter deposits some to have the data as necessary which the possibility changes. As the name suggests, the read-only memory
16、once stores the data, only can read out, cannot change (EPROM, E2PROM of the same kind ROM may change, read in data - editor through certain method to pour). But the read-write memory may store or the readout as necessary.In fact, the people often are called the logic unit and the controller merge c
17、entral processing element - CPU. The monolithic integrated circuit besides carries on the operation, but also must complete the control function. Therefore cannot leave counts with fixed time. Therefore, has the timer concurrently counter in the monolithic integrated circuit on the establishment, it
18、s basic structure with this serializes (2) center to give an example to be similar. To here up to, we had already known the monolithic integrated circuit basic composition, namely the monolithic integrated circuit was by the central processor (namely in the CPU logic unit and controller), the read-o
19、nly memory (usual expression is ROM), the read-write memory (called stochastic memory usual expression is RAM), the input/The outlet (also divides into the parallel mouth and the serial mouth, the expression is I/O) and so on composition. In fact inside the monolithic integrated circuit also has a c
20、lock electric circuit, causes the monolithic integrated circuit when carries on the operation and the control, all can have the rhythm to carry on. Moreover, but also has the interruption system so-called, this system has the reception room function, when when the monolithic integrated circuit contr
21、olled member parameter arrives the condition which some needs to perform to intervene, may pass through this the reception room the notification to give CPU, causes CPU to act according to exterior situation the things have their order of priority to adopt suitably deals with the measure.Now, we alr
22、eady had known the monolithic integrated circuit composition, how -odd under question was connects theirs each part the interdependence the whole? In fact, the monolithic integrated circuit interior has to connect them the link, namely so-called internal main line. This main line has like the big ci
23、ty the yang or male principle, but CPU, ROM, RAM, I/O, the interruption system and so on distributes in this the main line both sides, and connect with it. Thus, all instructions, the data all may pass through the internal main line transmission, has like in the big city each kind of goods transmiss
24、ion all to carry on after the yang or male principle.Second section monolithic integrated circuit command system and assembly language procedureFront already narrated the monolithic integrated circuit several main constituent, these parts constituted the monolithic integrated circuit hardware.
