Method for managing isolation of resources of system-on-chip and corresponding system-on-chip

A system on chip includes: at least one master device; at least one slave resource; an interconnect bus including an error notification channel; and a resource isolation system comprising, for each resource, a protection circuit configured to block or transmit transactions addressed to the resource according to access rights of the resource and access rights of transactions addressed to the resource via the interconnect bus. The protection circuit can generate a notification signal on an error notification channel of the interconnect bus while blocking the transaction. 一种片上系统包括：至少一个主设备；至少一个从资源；包括错误通知通道的互连总线；以及资源隔离系统，该资源隔离系统针对每个资源包括保护电路，该保护电路被配置为根据资源的访问权限以及经由互连总线被寻址到资源的事务的访问权限，阻止或传输被寻址到资源的事务。保护电路能够在对事务进行阻止的情况下，在互连总线的错误通知通道上生成通知信号。
