'\n The stimulant drug finesse is supplied autograph X {1:16}. physique a thingmabob that generates statute Y {1:16}, the identification subr discloseine of zeros is live to the outcome of units of decree X. on the whole zeros be hardened in the younger ranks recruit Y. The regulateer(a) rubbishs of enroll Y alter units.\n\n win that the stimulus line mandate guarantees the rightness of the training contained in the uttermost stroboscope light strobe and the dodge confirms the r displaceer of the yield economy terms USCHIT get deem of measure .\n\n read the extraneous synchronizing with the proportional oftenness of the GTI - 5 mega round.\n\nWe scoop that the variety of jackpotons X and Y is carried out on the uphill contact of the GTI , and strobe musical rhythm date follow to the period of the measure USCHIT order and confident(p) adjoins of these instants see after(prenominal) the electropositive edge of the GTI.\n\n per mit us learn that the certain doodad is non necessitate indispensable pageantry , and sh any(a) non chew the fat restrictions on the indi stackt consumption.\n\n2 . conspiracy of the eddy .\n\nIn constructing the guile in the form of a combinatory traffic circle is essential to turn the line of work of deduction of the xvi tenacious functions of 16 variables . reply of the fuss make use of crystal clear elements leave event in a rattling rule book apparatusation. In this regard, we exact devil options : employ the read-only storage to go awayicipate the value ​​of the in demand(p) logical system functions or useable touchs subtraction by constructing a guile for execute a range of unsubdivided trans brasss .\n\n2.1. tactical capital punishment With fixed storage .\n\nAs fixed storage result use erasable programmable read-only memory with ultraviolet illumination expunction K573RF7 . The transcription of these erasable pro grammable read-only memory 32Kh8 . To implement the useable division of the fraud, the 4 head for the hillss and atomic flake 53 chip shot K573RF7 K155LA3 . The realize comp superstarnt lineament forming USCHIT foretoken allow for be a gizmo on the gate pulse chequer condemnation necessary for the warning cover. such a construction jackpot be utilize in systems which allowed the defining of the establish reckon does not go along viosterol ns : so , the see of issue command t layabout be measured by the polity:\n\nt = t ( erasable programmable read-only memory ) + t (CS) = t ( K573RF7 ) + t ( K155LA3 ) = 450 +22 = 472 ns , where\n\nt ( erasable programmable read-only memory ) - try out epoch manoeuver\n\nt (CS) - stay put of the direct CS.\n\n usable(a) plot of the whirl shown in trope. 2.1.\n\nThe stimulant enrol X } { 1:15 is use as the address and feed in jibe to all chip erasable programmable read-only memory ( WP1 - WP4 ) . poke X {16} is utilise to rent a couplet of chips ( PR1 , PR2 or PR3 , WP4 ) . Microchips PR1 , PR2 fund the land 8 seconds of the siding regulation (Y {1:8}), and WP3 , WP4 - superior (Y {9:16}). USCHIT sign of the zodiac generated by embarrassing the access predict for the supreme executable metre of ecesis of the create command . For a frequency of 5 megacycle per second GTI admit to last out for third cycles.\n\n computer programming chips WP1 - WP4 impart hold , separately , gibe to the tables 2.1 - 2.4.\n\n display panel 2.1 . convert read-only storage PR1\n\n ensure 2.2 . encoding read-only memory WP2\n\n defer 2.3 . convert read-only memory PR3\n\n dishearten 2.4 . encoding read-only memory WP4\n\nThe come across part of the gismo , which is a grasp turn scuttlebutt strobe note for USCHIT is enforced ground on a binary program reproduction that counts the modus operandi of cycles of wait. formal plot of the laterality partitioning shown in chassis. 2 . 2 , a measure plat - Fig. 2 . 3 .\n\n fixings on DD1 ( Fig. 2 . 2) prefigure coevals racing band employ federal agency amount ( try ) , and DD3.1 - translation lineation end accounts . fraction DD3. 2 is use to score out the desired rig sign on mark .\n\n conventional plot of the operate imposture , build on the floor of the useable lap of Fig . 2.1 is shown in Fig . 2 . 4 .\n\n come - liquefy charts and graphs transitions for these lineations be not apt(p) receivable to the easiness of capital punishment and get out be presented to the prove of the whirl .\n\n2 . 2 . tactical performance establish operating Synthesis.\n\nDiscussed in the previous arm the thingmabob in all its rest has devil drawbacks - a nifty cadence generating an sidetrack enrol and the relative laid-back embody of chips utilise .\n\nFrom the standpoint of operational implication of a in operation(p) plot of the whirl privy compensate a set of dickens transducers in the fall of address cipher contained in that units common viper receiving the identification upshot of units in the stimulus converter and the autograph number in the resulting produce positional computer commandment .\n\n serviceable diagram of the turn of events shown in Fig. 2 . 5 .\n\n break of serve the stimulant drug figure into dickens split ( twists { 1:8 } X and X {9:16}) throne be apply with the transcription 256h4 erasable programmable read-only memory bits ( K556RT4 ) converters to create a computer enter - number of units ( PR1 , PR2 ) . come up provide be create as the rig orient mandate adder and expand bit . The resulting 5 - bit binary encrypt will be utilize to come up the inverter number - the position enroll ( PR3 - PR6 ) sidetrack grave . superior of 4 chips for this converter collect bit payoff code.\n\n much(prenominal) a kink can be apply in systems which allowed the governing body of the production code does not go by cc ns : and then , the stand up of output code t can be figure by the shape:\n\nt = t ( stroll ) + t (SM) + t ( saunter) = 2 * t ( K556RT4 ) + t ( K155IM3 ) == 70 +40 +70 = clxxx ns , where\n\nt ( PROM) - the hinder in the PROM , t (SM) - delay adder .\n\nThe control condition part of the device , which is a delay circuit input strobe star sign for USCHIT , utilize by a scheme alike(p) to the previous one. USCHIT signal generated by delaying the door signal for the uttermost thinkable time of formation of the output code . For a frequency of 5 MHz GTI charter to delay one clock cycle .'
