Publication number: 20110154299Abstract: An instrumentation apparatus and method capable of adding an additional operation to an execution program, are provided. A processor for supporting instrumentation assigns an instrumentation bit to an instruction that includes instrumentation code that needs to be executed. The processor jumps to an address of a memory for execution of the instrumentation code, and stores the jump address in a register. If a fetched instruction includes the instrumentation bit, the processor jumps to the jump address stored in the register and executes the instrumentation code.Type: ApplicationFiled: August 16, 2010Publication date: June 23, 2011Applicant: SAMSUNG ELECTRONICS CO., LTD.Inventors: Hyo-Young KIM, Sung-Do Moon, Jung-Gyu Park
