Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
155 words
A memory system, comprising; a plurality of memory blocks, each memory block storing a plurality of information units, means for receiving an address which designates one information unit stored in one of said memory blocks, a plurality of address producing means, each having an arithmetic function, means for supplying said address received at said address receiving means to each of said address producing means in common, means for generating a plurality of data to be added to or subtracted from said address, means for supplying said data to respective address producing means, each of said address producing means performing an arithmetic operation using said address and said supplied data to produce a new address, respectively, means for applying the new addresses produced by said plurality of address producing means to respective memory blocks, and means for simultaneously reading a plurality of information units designated by said new addresses out of said plurality of memory blocks.
Claim 2
Dependent Claim
155 words
A memory system, comprising; a plurality of memory blocks, each memory block storing a plurality of information units, means for receiving an address which designates one information unit stored in one of said memory blocks, a plurality of address producing means, each having an arithmetic function, means for supplying said address received at said address receiving means to each of said address producing means in common, means for generating a plurality of data to be added to or subtracted from said address, means for supplying said data to respective address producing means, each of said address producing means performing an arithmetic operation using said address and said supplied data to produce a new address, respectively, means for applying the new addresses produced by said plurality of address producing means to respective memory blocks, and means for simultaneously reading a plurality of information units designated by said new addresses out of said plurality of memory blocks.
Claim 3
Dependent Claim
124 words
An image processing system, comprising; memory means for storing a plurality of image data to be displayed; means for receiving a center address designating one image data within said plurality of image data; means for producing peripheral addresses designating a plurality of peripheral image data adjacent to said one image data designated by said center address; means for reading said one image data and said plurality of peripheral image data out of said memory means, simultaneously, according to said center address and said peripheral addresses; means coupled to said reading means for arranging the plurality of read-out image data according to the order in which they are to be displayed; and display means coupled to said arranging means for displaying the arranged image data.
Claim 4
Dependent Claim
124 words
An image processing system, comprising; memory means for storing a plurality of image data to be displayed; means for receiving a center address designating one image data within said plurality of image data; means for producing peripheral addresses designating a plurality of peripheral image data adjacent to said one image data designated by said center address; means for reading said one image data and said plurality of peripheral image data out of said memory means, simultaneously, according to said center address and said peripheral addresses; means coupled to said reading means for arranging the plurality of read-out image data according to the order in which they are to be displayed; and display means coupled to said arranging means for displaying the arranged image data.
Claim 5
Dependent Claim
65 words
A memory system as claimed in claim 1, in which said plurality of address producing means are divided into a first group of row address producing means and a second group of column address producing means, one of said row address producing means and one of said column address producing means being coupled to a respective memory block by means of predetermined wiring paths, respectively.
Claim 6
Dependent Claim
34 words
A memory system as claimed in claim 1, in which said generating means generates said plurality of data in accordance with the content of a portion of said address received at said receiving means.
