INFORMATION PROTECT METHOD OF MEMORY PROTECT REGION

摘要

An information protect method in a memory protect region is provided to configure a system at low costs by simplifying configuration of a cache and facilitate implementation in the other system such as a DSP(Digital Signal Processor) and DMA(Direct Memory Access) by simplifying an operation algorithm. An information protect method in a memory protect region comprises the following steps of: determining a prefetch signal for command access in an integrated cache(S600); determining an execution signal for access to data in the integrated cache; and determining whether a command pointer is present within the memory protect region(S620).
