Abstract: PROBLEM TO BE SOLVED: To prevent increase in side lobe in a far-field image or in the threshold current of a laser by making the refractive index of one light confining layer between an active region and one cladding region to be smaller than that of the other cladding region. SOLUTION: A laser device has two light confining layers 16, 17.

IPC: G06F12/08
Filed: 2000-02-10
Abstract: PROBLEM TO BE SOLVED: To provide an instruction level simulator for detecting the cache synchronization illegality of a self rewriting program for detecting the generation of a problem before viewing the executed result of an instruction. SOLUTION: An instruction analyzing means 1 reads the value of program counter from a pseudo register storing means 5, and reads an instruction code from a pseudo instruction cache storing means 3 by suing the read value as an instruction address. The instruction analyzing means 1 executes instruction analysis for decomposing the read instruction code into an operation code indicating the kind of the instruction and an operand indicating the register to be operated or memory address of the instruction, and checks whether or not data having the same address as the instruction address are stored in a pseudo data cache storing means 4. When the data having the same address as the instruction address are stored, the attribute is read, and whether or not the data is Dirty is judged.  When the read attribute is Dirty, a warning message that 'the instruction is executed in a state that the instruction cache is contradictory to the data cache' is outputted, and the contents are stored in an execution log storing means 7.
