Abstract
A structure and technique are provided for improving the average access time in a bubble lattice file (BLF) storage, and for providing reordering capability in the lattice file. The bubble lattice arrangement includes a translation structure for moving bubble domains in the lattice to various access channels where columns of bubble domains can be removed from the lattice. These are double access channels which remove two adjacent columns of bubble domains at the same time. A read means and a write means are associated with each channel of the double channel access for reading the information in each column removed from the lattice, and for writing new information into these columns. A transposition structure is provided for transposing the information represented by bubble domains in each of the removed columns, in response to a signal from associated control circuitry. The write means is responsive to the transposition means when it is desired to transpose the bubble information in each of the removed adjacent columns. Circuitry for transposition can be magnetic bubble circuitry on the magnetic lattice chip, or external control circuits.
