In addition, SGRAM is the abbreviation of Synchronous Graphics DRAM, mean that synchronous figure RAM is that kind aims at
The video memory of video card design, is a kind of stronger video memory of figure literacy, is improved by SDRAM.He improves over inefficient
The lower disadvantage of energy video memory transmission rate, to show that the raising of card performance creates condition.SGRAM is not to read one by one when reading and writing data
It takes, but is that unit improves the effect of graphics controller to reduce the number that memory is integrally read and write with " block " (Block)
Rate.But its design and manufacture cost is higher, is more to be applied to video card more high-end at that time.Current such video memory is also substantially
It is not used by manufacturer, replaced DDR video memory.SDRAM, i.e. Synchronous DRAM (synchronous DRAM), once
A kind of type of memory most widely used on PC computer, even if today SDRAM still also market occupy a seat it
Ground.Since being " synchronous DRAM ", that operating rate that just represent it is and system bus speed sync.
Sdram memory is divided into the different sizes such as PC66, PC100, PC133 again, and the subsequent number of specification just represents memory maximum
Institute's energy malfunctioning systems bus speed, such as PC100, that just illustrates that this memory can be in the computer that system bus is 100MHz
Middle synchronous working.It is that is, synchronous with system clock with system bus speed sync, unnecessary waiting week is avoided in this way
Phase reduces time data memory.Synchronization also makes storage control know used in which clock pulses phase by request of data, because
This data can just start to transmit in the pulse rising stage.SDRAM uses 3.3 volts of operating voltages, the DIMM interface of 168Pin, and bandwidth is
64.SDRAM is not only applied on memory, also relatively conventional on video memory.SDRAM can work asynchronously with CPU, N-free diet method week
Phase reduces data transfer delay.
Using stove power supply control platform of the invention, for household stove in the prior art, there are the technologies of security risk
Problem, on the basis of customizing image procossing mechanism, when recognizing stove scene and only existing baby's object, cutting pair rapidly
The power supply of stove damages to avoid to baby's object；It is particularly critical, also based on each target in image
Picture redundancy analysis as a result, using the target subgraph of the smallest preset quantity of redundancy as multiple output subgraphs,
In, signal noise ratio (snr) of image is inversely proportional with preset quantity；To solve above-mentioned technical problem.
It is understood that although the present invention has been disclosed in the preferred embodiments as above, above-described embodiment not to
Limit the present invention.For any person skilled in the art, without departing from the scope of the technical proposal of the invention,
Many possible changes and modifications all are made to technical solution of the present invention using the technology contents of the disclosure above, or are revised as
With the equivalent embodiment of variation.Therefore, anything that does not depart from the technical scheme of the invention are right according to the technical essence of the invention
Any simple modifications, equivalents, and modifications made for any of the above embodiments still fall within the range of technical solution of the present invention protection
It is interior.
