DEVICE FOR ASSOCIATIVE OPTICAL DATA ACCESS TO MEMORY UNIT Russian patent published in 1997 - IPC

FIELD: computer engineering. SUBSTANCE: device has multiple-channel light source 5, which is used for light input to device, optically controlled time-space light modulator 3 which displays pages of associative keys, picture converging unit 7 which provides possibility to represent output signals in para-phase code, picture converging unit 8 which distributes output pictures to different photodetectors 9, projection unit 2, beam generation unit 4 and focusing unit 6, photodetectors 9 which convert optical signals to electric ones, and control unit 10. Device provides possibility of associative search in large data base for multiple request keys. EFFECT: increased speed. 2 cl, 2 dwg
