Claims (5)
1. Laite ensimmäisen ja toisen mikroprosessorin (6,7) rinnakkaissynkronisen käytön aikaansaamiseksi tieto- 5 konejärjestelmässä, jossa mikroprosessorien kellotaajuus saadaan järjestelmäkellontaajuuden sisäisellä jaolla, tunnettu siitä, että laite käsittää kytkimen (4) systeemikellon signaalitien katkaisemiseksi vastaavasti sulkemiseksi toisen mikroprosessorin (7) kellosisäänmenoon, 10 sekä kytkimen (4) ohjaamiseksi loogisen piirin (3), jonka kaksi sisäänmenoa on liitetty mikroprosessorien (6,7) kel-loulostuloihin siten, että sisääntulojensa keskinäisen uroavuuden yhteydessä se ohjaa kytkintä (4) katkaisemaan järjestelmäkellon signaalitie kun taas kelloulostulojen 15 signaalien samankaltaisuuden yhteydessä se ohjaa kytkintä sulkemaan mainitun signaalitien, jolloin saavutetaan por-taattainen vaiheistus yhdessä rinnakkaissynkronismin kanssa.
2. Patenttivaatimuksen 1 mukainen laite, t u n - 20. e t t u siitä, että looginen piiri (3) muodostuu "negaa-tioivasta exklusiivisesta tai" -piiristä ja että kytkin (4) muodostuu "ja" -piiristä.
3. Patenttivaatimuksen 1 mukainen laite, tunnettu siitä, että kytkin (4) sisältyy jakavaan las- 25 kinpiiriin (5) käsittäen ensimmäisen ja toisen JK-kiikun kytkettyinä järjestelmäkellon ja mikroprosessorinsa kello-sisäänmenon väliin, jossa toisen JK-kiikun, jonka ulostulo on liitetty toiseen mikroprosessoriin (7), J- ja K-sisään-tulot on liitetty loogisen piirin (3) ulostuloon, jolloin . 30 mainittu toinen JK-kiikku suorittaa kytkimen (4) toimin non .
