Address transformation for memory accessing

摘要

A method and system for memory access comprising address transformation means for generating a single value of memory address y from one or more corresponding values of an input quantity x, in which the number of values of the input quantity that correspond to a single value of the memory address varies across the range of values of the input quantity. The relationship between an input quantity and the corresponding memory address may be characterised as a hyperbolic function. Different hyperbolic functions may be used either side of a boundary value s. A transformation circuit is described (Fig 2). The memory may be used to track the source of data, by storing data for identifying fragments of data packets received according to the Internet Protocol.
