Dynamic resource sharing

摘要

Representative implementations of devices and techniques provide dynamic secure sharing of resources. A resource module can be partitioned into a plurality of functional blocks, which may be allocated to non-secure and secure applications. A security monitor can monitor processor activity and determine when secure resources may be accessed.

主权项

1. An apparatus, comprising:
a snooper component arranged to monitor a processor and to determine whether an application executing on the processor requests secure access to a resource; and an output component arranged to output a secure-mode signal granting secure access to secure functional blocks of shared resource modules when the application is a secure application, wherein the shared resource modules are partitioned into secure functional blocks and non-secure functional blocks, the secure functional blocks being accessed by secure applications concurrent to the non-secure functional blocks being accessed by non-secure applications, and wherein the secure functional blocks are communicatively isolated from the non-secure functional blocks.
