The low achievement consumes introduction

Phenomenon a:We this system is a 220 V power supply, need not care the achievement consumed a problem

Order to review:Is low achievement consume a design combine not only only for saving an electricity, more advantages lie in lowered the power mold piece and heat elimination system of become

Originally, because the electric current let up to also reduced the interference of the electromagnetism radiation and hot Zao voice.Because the equipments temperature lowers, the spare part life span then corresponds extension(the work temperature of semi-conductor spare part raises 10 degrees each time, the life span then shortens a half)

Phenomenon two:These total line signals all pull with the electric resistance for a while, feel to trust some

Order to review:The signal needs the reason that the top and bottom pulls a lot of, but is not a s either to all want to pull.Up and down pull electric resistance to pull a pure importation signal, electric current also several less than ten tiny Annes, but pull a signal that is driven, its electric current will reach the milli- Anne class, the system in nowadays is usually an address data is 32 for each, probably still have 244|245 insulate behind of total line and other signals, words all up pull, several tiles of achievement consume and then consume on these electric resistances.(the idea that didn't want to use 8 hair money to once give or get an electric shock to treat this several tiles of achievement consume)

Phenomenon three:CPU and FPGA of these need not of I|how to handle O?Make it empty first, hereafter say again

Order to review:Need not of I|O if hanging is empty, be subjected to outside little interference and then may become again and again flapping to concuss of importation signal

, But the achievement of the MOS spare part consume basic be decided by the inside out number of times of an electric circuit.If pull it up, each one's leading feet will also have the electric current of tiny Anne class, so the best way is to establish output(certainly outside can not connect an other to have driving signal)

Phenomenon four:This FPGA still remains so several inexhaustibilities, can heartily develop

Order to review:FGPA of achievement consume and be used of trigger the amount of machines and it inside out number of times become direct proportion, so the same FPGA of model number at different electric circuit dissimilarity time of achievement consume may differ 10000%.Reduce high speed to inside outly trigger the amount of machines as far as possible is lower FPGA the achievement consumes of root method.

Phenomenon five:The achievement of these small chips consumes all very low, need not consider

Order to review:It is a very difficult assurance to consume to not that complicated chip achievement in the inner part of, it mainly from lead electric current on feet assurance, an ABT16244, there are no the words loading consuming electricity probably not arrive 1 milli- Anne, but its index sign is each feet to drive 60 milli- Anne's loads(if match several electric resistances of ten mus in Europe), namely full burden of achievement consume biggest can reach to 60*16=960 mas, certainly be just the power electric current so big, the calorieses all fell load in the body.

Phenomenon six:The saving machine controled signal so more, I this needs to be as all right as WE signal with the OE, the slice chooses and then connects ground, while reading an operation like this the data comes out quickly much.

Order to review:Being big part of to save the achievement of machine to consume to choose in the slice would choose than the slice while being effective(in spite of how OE and WE are) invalid big 10000% above, so should use CS possibly to control chip, and at satisfy other shorten the width that the slice chooses pulse possibly under the circumstance of requests.

Phenomenon seven:How to all was blunt these signals?As long as match well, can get rid of

Order to review:In addition to minority of particular signals(is like 100 bases-T, CML), it is blunt to is all once having, if not that being very big, different choose site for capital to need to be matched, even if match don't  want to match as well had better.The exportation resistance of elephant TTL doesn't arrive 50 mus in Europe and have of even 20 mus in Europe, if also use to so greatly match electric resistance, that electric current very big, achievement consume can not accept, another signal range also will small must can not use, again say that the general signal is outputsing Gao Dian Ping-ho to don't same alike output low electricity exportation resistance at ordinary times, can't attain to completely match as well.So only once attained to the TTL, LVDS, 422 etc. signals' matching blunt can accept then
