Claims
- 1. A dynamic random access memory (DRAM) organized as at least one bitstream buffer for storing a plurality of bytes and at least one picture buffer for MPEG decoding, said DRAM comprising d memory devices, each device having r rows and c columns with b bits per cell and p picture samples, where
- b*d is divisible by 8, and
- r*c is larger than a sum of the size of the at least one bitstream buffer in bytes and one of 2 and 3 times 1.5*1*p divided by (b*d/8).
- 2. The dynamic random access memory as defined by claim 1, said memory storing first and second reference picture (A,B) components (U,V,Y) organized first along a device axis (d) and then along rows (r) with one or more complete lines of a reference picture component occupying the same row, with the memory region occupied by each component being rectangular.
- 3. The dynamic random access memory as defined by claim 2, said memory storing third reference picture (C) components (U,V,Y) organized first along a device axis and then along rows and occupying a largest possible part of each row in multiples of 8*(8/(b*d)).
