`ABSTRACT
`(57)
`
`
`An electronic system, an integrated circuit and a method for
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`display are disclosed. The electronic system contains a first
`device, a memory and a v1deo/aud1o compression/decom-
`
`
`
`
`
`pression device such as a decoder/encoder. The electronic
`
`
`
`
`
`
`system is configured to allow the first device and the video/
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`audio compression/decompression device to share the
`
`
`
`
`
`
`
`memery- The eleetrenie System may be ineluded in 3‘ eem'

`Puter 11} Whlch 031:? L11:Igemory 15 31 mam memory; 1t‘/Emory
`access 1s accomp 1s e
`y one or more memory 1n e aces,
`
`
`
`
`
`
`direct coupling of the memory to a bus, or direct coupling of
`
`
`
`
`
`
`the first device and decoder/encoder to a bus. An arbiter
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`selectively provides access for the first device and/or the
`
`
`
`
`
`
`
`
`decoder/encoder to the memory based on priority. The arbiter
`
`
`
`
`
`
`may be monolithically integrated into a memory interface.
`The decoder may be a video decoder configured to comply
`
`
`
`
`
`
`
`the
`standard. The memory may store predicted
`
`
`
`
`
`
`
`images obtained from a preceding image.
