Method and apparatus for efficient data storage

Claim 1

An apparatus for displaying messages on a display device in which each message is a display comprised of a plurality of individual message words in at least one line, comprising: a first addressable message word memory for individually storing each of said message words contained in said messages, with each word comprising a plurality of binary-coded characters; a second addressable word pointer memory for storing the address of the first binary-coded character in each of said message words stored in said first memory; a third addressable memory for storing a plurality of data code representations, each of which points to an address in said second memory which in turn provides an address for said message words which define a particular message to be displayed, and also for storing a plurality of control code representations which define the relative positioning of said message words with respect to each other on said display device; a buffer for storing assembled message words for subsequent display on said display device; data bus means operatively coupling said first, second and third memory means and said buffer; and data processor means coupled by said data bus means to said first, second and third memory and to said buffer for addressing said third addressable memory to obtain said data and control code representations and to use said data code representation to address said second memory to obtain further addresses, to use said further addresses to retrieve the message words from said first memory, and to use said control code representation to position in said buffer the retrieved message words to display a particular message.

Claim 2

An apparatus for displaying messages on a display device in which each message is a display comprised of a plurality of individual message words in at least one line, comprising: a first addressable message word memory for individually storing each of said message words contained in said messages, with each word comprising a plurality of binary-coded characters; a second addressable word pointer memory for storing the address of the first binary-coded character in each of said message words stored in said first memory; a third addressable memory for storing a plurality of data code representations, each of which points to an address in said second memory which in turn provides an address for said message words which define a particular message to be displayed, and also for storing a plurality of control code representations which define the relative positioning of said message words with respect to each other on said display device; a buffer for storing assembled message words for subsequent display on said display device; data bus means operatively coupling said first, second and third memory means and said buffer; and data processor means coupled by said data bus means to said first, second and third memory and to said buffer for addressing said third addressable memory to obtain said data and control code representations and to use said data code representation to address said second memory to obtain further addresses, to use said further addresses to retrieve the message words from said first memory, and to use said control code representation to position in said buffer the retrieved message words to display a particular message.

Claim 7

An apparatus for displaying a message comprising a plurality of individual message words on a display device, comprising: display means; first data processing means for causing the display of message words in a predetermined locational relationship on said display means; buffer means for temporarily storing information to be transmitted to said display means under control of said first data processing means; first memory means for storing a plurality of individual message words which comprise said information to be displayed on said display means; second memory means for storing message word addresses and control code representations for assembling the message words from said first memory means into messages; data bus means operatively coupling said display means, said first data processing means, said buffer means and said first and second memory means; and second data processing means operatively coupled by said data bus means to said buffer means for controlling the exchange of message words and control code representations to said buffer means from said first and second memory means, for controlling the addressing of said first and second memory means and for controlling the transmission of message words to said first data processing means through said buffer means for the display of messages on said display means.

Claim 8

An apparatus for displaying a message comprising a plurality of individual message words on a display device, comprising: display means; first data processing means for causing the display of message words in a predetermined locational relationship on said display means; buffer means for temporarily storing information to be transmitted to said display means under control of said first data processing means; first memory means for storing a plurality of individual message words which comprise said information to be displayed on said display means; second memory means for storing message word addresses and control code representations for assembling the message words from said first memory means into messages; data bus means operatively coupling said display means, said first data processing means, said buffer means and said first and second memory means; and second data processing means operatively coupled by said data bus means to said buffer means for controlling the exchange of message words and control code representations to said buffer means from said first and second memory means, for controlling the addressing of said first and second memory means and for controlling the transmission of message words to said first data processing means through said buffer means for the display of messages on said display means.
