Title:
SECURITY METHODOLOGY TO PREVENT USER FROM COMPROMISING THROUGHPUT IN HIGHLY THREADED NETWORK ON CHIP PROCESSOR
Document Type and Number:
Japanese Patent JP2010102694
Kind Code:
A
Abstract:
To provide a method executed by a computer, a system and a computer program, for preventing an untrusted work unit message from compromising throughput in a highly threaded Network On a Chip (NOC) processor.
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 predetermined 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.
