PROTECTION SCHEME FOR EMBEDDED CODE |
摘要 |
A code protection scheme for controlling access to a memory region in an integrated circuit includes a processor with an instruction pipeline that includes multiple processing stages. A first processing stage receives one or more instructions. A second processing stage receives address information identifying a protected memory region of the memory from the first processing stage and protection information for an identified protected memory region. The protection information indicates a protection state assigned to each protected memory region. Based on the instruction type of the received instruction and the protection information associated with a particular protected memory region, the second processing stage determines whether to enable or disable access to the particular protected memory region by the processor or other external host. |
