ABSTRACT:
The present invention discloses a method and system for observing and measuring in real-time an event inside a processor via an observation architecture (OA). The method comprises the steps of: (1) receiving a command instruction; the command instruction includes at least an opcode and an operand specifier; (2) decoding the command instruction by converting the opcode into control bits; (3) mapping the operand specifier to select at least one resource element of the observation architecture; and (4) capturing the event according to the control bits.
