FIELD: engineering of methods and devices for monitoring efficiency of multithreaded processor, performing commands from two or more threads concurrently.
SUBSTANCE: device for monitoring has central microprocessor unit, engineered for processing multiple threads concurrently, a set of programmable event counters, registers for controlling operation of aforementioned event counters, access cell, meant for offering access to event counters to determine current result of count. Events are classified in accordance to their thread identification and current level of thread privileges. Each classified event is counted by means of one of several programmable event counters, which track all processor events, monitoring of which is performed.
EFFECT: possible detection of flow and level of privileges, at which event occurs, characterizing efficiency of processor.
