1Loss of energy
If image data is compressed using a block-based compression scheme, then bandwidth consumption and power usage are reduced, but the system requires dual addressing schemes (spatial coordinate and block-based coordinate) which complicates data access
Solution Approach 1:
The patent introduces an interface apparatus as an intermediary component between the compressed data storage system and the processing system. This interface apparatus contains address translation circuitry that automatically converts spatial coordinate addressing requests into block-based coordinate addressing requests, shielding the processing system from the complexity of dual addressing schemes while enabling compressed data access
Solution Approach 2:
The interface apparatus creates and maintains a mapping between spatial coordinate addresses and block-based coordinate addresses. This mapping acts as a copy or translation layer that allows the system to use simple spatial coordinate addressing while internally translating to the appropriate block-based addresses for accessing compressed data
2Volume of stationary object
If image data is compressed and stored, then storage space requirements are reduced, but access to the compressed data becomes less efficient due to the need for block-based addressing
Solution Approach 1:
The interface apparatus serves as a mediator that handles the conversion from spatial coordinate addressing (natural for image processing) to block-based addressing (required for compressed data). This intermediary layer maintains ease of operation for image processing tasks while enabling efficient access to compressed data through automatic address translation
Solution Approach 2:
The system performs preliminary compression of image data into block-based format for efficient storage, while the interface apparatus is pre-configured with address translation capabilities that automatically handle the conversion back to spatial coordinates when data is needed, making the compression transparent to the processing system
Data Source
AI summary
An interface apparatus and method of operating the same are provided. The interface apparatus receives an uncompressed image data read request using a first addressing scheme at a first bus interface and transmits a compressed image data read request using a second addressing scheme from a second bus interface. Address translation circuitry translates between the first addressing scheme and the second addressing scheme. Decoding circuitry decodes a set of compressed image data received via the second bus interface to generate the set of uncompressed image data which is then transmitted via the first bus interface. The use of a second addressing scheme and image data compression is thus transparent to the source of the uncompressed image data read request, and the interface apparatus can therefore be used to connect devices which use different addressing schemes and image data formats, without either needing to be modified.
