Appeal No. 97-0801
Application 08/168,087
October 5, 1995 and was entered by the examiner.
The disclosed invention pertains to a moving picture decoding device for decoding a moving
picture by writing and reading picture data to and from a picture memory. More particularly, the
picture memory comprises a synchronous dynamic random access memory (SDRAM) having a
plurality of banks of memory. The invention is particularly directed to the manner in which a bank
switching address is stored in the memory for permitting continuous reading of the banks of memory in
alternation.
Representative claim 1 is reproduced as follows:
1. A moving picture decoding device for decoding a moving picture by writing and reading
picture data to and from a picture memory, wherein the improvement comprises:
a synchronous dynamic random access memory used as the picture memory, wherein
the synchronous dynamic random access memory has a plurality of banks, each of the banks is
accessed by a common column address and a common row address, each bank designated by a bank
switching address, each predetermined length of the picture data is written into only one of the plurality
of banks, and the picture data is continuously read from the plurality of banks in alternation.
The examiner relies on the following references:
