Abstract

Abstract A neighbor image processing exclusive memory device comprises a data input/output device for supplying and receiving image data; a plurality of memory blocks coupled to the data input/output device for receiving, storing and transmitting neighbor image data via the data input/output device, individual segments of the data having corresponding addresses; and a plurality of address converters coupled to the memory blocks for selectively reading, writing and converting addresses in response to conversion mode signals received from an external source thereof. The converters simultaneously supply the addresses to the memory blocks for simultaneous access to individual segments of the neighbor image data in the memory blocks.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 162 words
A neighbor image processing exclusive memory device, comprising: data input/output means for supplying and receiving image data; memory means, coupled to said data input/output means, for receiving, storing and transmitting neighbor image data via said data input/output means, individual segments of said data having corresponding addresses, wherein said memory means includes a plurality of independent memory blocks; and address conversion means, coupled to said memory means, for selectively reading, writing and converting said addresses in response to conversion mode signals received from an external source, said conversion means simultaneously supplying said addresses to said memory means for simultaneous access to individual segments of said neighbor image data in said memory means, said conversion means including an individual address converter corresponding to each memory block, a conversion table for receiving said conversion mode signal, and a pair of adders coupled to said conversion table for receiving the output thereof and for receiving said addresses corresponding to the data input into said memory means.
Claim 2
Dependent Claim 162 words
A neighbor image processing exclusive memory device, comprising: data input/output means for supplying and receiving image data; memory means, coupled to said data input/output means, for receiving, storing and transmitting neighbor image data via said data input/output means, individual segments of said data having corresponding addresses, wherein said memory means includes a plurality of independent memory blocks; and address conversion means, coupled to said memory means, for selectively reading, writing and converting said addresses in response to conversion mode signals received from an external source, said conversion means simultaneously supplying said addresses to said memory means for simultaneous access to individual segments of said neighbor image data in said memory means, said conversion means including an individual address converter corresponding to each memory block, a conversion table for receiving said conversion mode signal, and a pair of adders coupled to said conversion table for receiving the output thereof and for receiving said addresses corresponding to the data input into said memory means.
Claim 3
Dependent Claim 16 words
The processing device of claim 1 wherein each of said memory blocks comprises a 512×512-bit RAM.
