Method and computer program for managing a virtual address used to program a DMA controller and associated system on a chip.

摘要

The virtual address is divided into two bit fields. Address words (A1, A2) of N bits are created for respective bit fields. The bits include distinct prefixes (pref1, pref2) having a given value associated to the fields and coded with a number strictly greater than one. A direct memory access (DMA) controller programming is executed using storing instructions having respective address words created for the respective fields. Independent claims are also included for the following: (A) a computer program having a DMA controller programming from a virtual address among a source virtual address; (B) a system-on-chip having a CPU.
