Abstract
A system is provided that includes a processor and a random access memory (RAM) coupled to the processor. The RAM is divided into public RAM and secure RAM. The system also includes a system memory coupled to the processor, wherein the system memory stores RAM resize instructions that, when executed, enable the public RAM and the secure RAM to be dynamically resized. The system memory may also store save/restore secure RAM instructions that, when executed, perform a save operation that saves the secure RAM to non-volatile memory and a restore operation that restores the secure RAM from the non-volatile memory. The system memory may also store arbitration instructions that, when executed, enable a cryptographic hardware accelerator (HWA) to be shared by a secure application and a public application.
