SECURITY METHODOLOGY TO PREVENT USER FROM COMPROMISING THROUGHPUT IN A HIGHLY THREADED NETWORK ON A CHIP PROCESSOR

摘要

A computer-implemented method, system and computer program product for preventing an untrusted work unit message from compromising throughput in a highly threaded Network On a Chip (NOC) processor are presented. A security message, which is associated with the untrusted work unit message, directs other resources within the NOC to operate in a secure mode while a specified node, within the NOC, executes instructions from the work unit message in a less privileged non-secure mode. Thus, throughput within the NOC is uncompromised due to resources, other than the first node, being protected from the untrusted work unit message.
