Dynamic random access memory for MPEG decoding

摘要

A dynamic random access memory (DRAM) for use in MPEG decoding includes d devices each having r rows and c columns with b bits per cell and p samples, where b*d is divisible by 8 and r*c is larger than a sum of upstream buffers in bytes and either 2 or 3 times 1.5*1*p divided by (b*d/8). First and second reference picture components are organized first along a depth axis (d) and then along rows (r) with complete lines of a component occupying the same row with the memory region occupied by each component being rectangular and third reference signal components are organized first along a depth axis and then along rows and occupying a largest possible part of each row in multiples of 8*(8/(b*d)).
