Abstract
A multitenancy system that includes a host provider, a programmable device, and multiple tenants is provided. The host provider may publish a multitenancy mode sharing and allocation policy that includes a list of terms to which the programmable device and tenants can adhere. The programmable device may include a secure device manager configured to operate in a multitenancy mode to load a tenant persona into a given partial reconfiguration (PR) sandbox region on the programmable device. The secure device manager may be used to enforce spatial isolation between different PR sandbox regions and temporal isolation between successive tenants in one PR sandbox region.
