The execution unit execute the instruction while the bus interface unit do the fetching and shows the results as an output
about instruction execution time
In the 8086/8088, the execution unit is the part of the processor known as the CPU. It executes the instructions and generates the results. The bus interface unit, on the other hand, is the part of the processor that handles reading and writing to memory. The two are somewhat loosely coupled, with the bus interface unit attempting to always be ahead of the execution unit, i.e. using the cache, so that the execution unit's wait time is minimized and performance is maximized.
The execution of the program starts with function main, wherever it is in the source.
No; the execution does.
To programmatically stop the execution of a MATLAB program, you can use the "return" statement or the "error" function to exit the program at a specific point. This will halt the execution and return control to the calling function.
In C, function execution ends with the return statement or when execution encounters the last brace, }, that matches the opening brace, {. If the function is typed, such as int myfunc(), then encountering the last brace is considered an error, because that sequence returns no value.
biu stands for bus interface unit and eu stands for execution unit. In 8086 microprocessor BIU fetches the instructions and places in the queue. The Eu executes the fetched instruction and places the result in the registers
the unit impulse function g(t)
It starts with function 'main'.
That's up to you, but the execution of the program begins with function main.
