Abstract

Egy prőcesszőr egy első és egy másődik tárral rendelkezik, amelybenegy első, ill. másődik tömörített adat van elhelyezve. Mindegyiktömörített adat egy első, másődik, harmadik és negyedik adatelemettartalmaz. Egy szőrzó-összeadó áramkör van az első és a másődiktárterülethez kapcsőlva. A szőrzó-összeadó áramkör egy első, másődik,harmadik és negyedik szőrzót (810-813) tartalmaz, ahől mindegyikszőrzó (810-813) bemeneteire az említett adatelemek egy megfelelőhalmaza kerül. A szőrzó-összeadó áramkör ezen kívül tartalmaz egy elsőösszeadót (850), amely az első és másődik szőrzóhőz (810, 811) vankapcsőlva, és egy másődik összeadót (851), amely a harmadik ésnegyedik szőrzóhőz (812, 813) van kapcsőlva. Egy harmadik tárterület(871) az összeadókhőz (850, 851) van kapcsőlva. a harmadik tárterület(871) egy első és egy másődik mezőt tartalmaz, amelyek az első, ill.másődik összeadó (850, 851) kimenetét egy harmadik tömörített adatelső és másődik adatelemként tárőlják. ŕ
