The operation principle of the arithmetic operating apparatus of the power line edge signal triggering of the present embodiment is as follows：
When the arithmetic unit is not upper electric, the power supply electrical level that charhing unit provides is low level, now initially
Change unit and edging trigger arithmetic element electricity shortage, whole arithmetic unit are unable to computing.
When electric on arithmetic unit, and when edge signal is high level, the energy-storage travelling wave tube in charhing unit
C is electrically charged.In the case of high level lasting time is sufficiently long, power supply electrical level is height by low level upset
Level, initialization unit and edging trigger arithmetic element are by normal power supply.
Now, the metal-oxide-semiconductor T3 conductings in initialization unit, turn on metal-oxide-semiconductor T2, therefore,
Charhing unit can be charged by current-limiting resistance R to the metal-oxide-semiconductor T4 as electric capacity.To metal-oxide-semiconductor
In T4 charging processes, the voltage of metal-oxide-semiconductor T4 grids gradually increases, and make it that second is anti-when being charged to reach
The reset signal of phase device V2 outputs completes initialization after being overturn by low level to high level.
Second phase inverter V2 output end and the reset of each d type flip flop in edging trigger arithmetic element
End connection, when the second phase inverter V2 exports low level, each d type flip flop resets, i.e. edging trigger
Arithmetic element is reset.
Fig. 6 is edge signal, initialization unit and three adders that power line inputs in the present embodiment
The time diagram of operation result when the Schema control constant of B group inputs is Binary Zero 01, wherein transporting
Result is calculated to represent using the output signal of the positive output end of three d type flip flops.After power supply electrifying,
Three d type flip flops of T time are reset to logical zero, i.e. operation result is reset.In the rising edge of edge signal
At E1, operation result is Binary Zero 01；Rise on the power line along E2, operation result is Binary Zero 10；
Rise on the power line along E3, operation result is Binary Zero 11；Rise on the power line along E4, computing knot
Fruit is binary one 00；Rise on the power line along E5, operation result is binary one 01；On the power line
Rise along E6, operation result is binary one 10；Rise on the power line along E7, operation result is binary system
111；Rise on the power line along E8, arithmetic unit overflows, and operation result is Binary Zero 00, power line
