A hardware emulator having: a verification target circuit that includes a CPU in which progress of instruction execution is controlled by a program counter, and a circuit that operates according to the instruction execution by the CPU; at least one replica circuit that is formed by replication of the verification target circuit; a debug controller that starts operation of the verification target circuit upon receipt of an operation start signal from an outside of the hardware emulator, and that stops operation of the verification target circuit and the replica circuit when a value of the program counter of the verification target circuit reaches a predetermined breakpoint; an execution start delaying portion that causes the replica circuit to start execution of an instruction with a delay equivalent to a predetermined number of instructions after the verification target circuit starts execution of the same instruction; a program counter controller that performs control so that the value of the program counter of the verification target circuit and a value of a program counter of the replica circuit are simultaneously updated when both of the verification target circuit and the replica circuit complete the execution of their respective running instructions; and an output portion that sends an output from any one of the verification target circuit and the replica circuit to the outside of the hardware emulator in response to a request from the outside of the hardware emulator.
摘要:
It is an object of the present invention to suppress an abrupt gain change and smoothly and highly accurately control transmitted electric power even if the transmitted electric power greatly changes when a closed loop control that crosses the threshold value as the detection limit of the transmitted electric power.The transmitted electric power of a self-station is detected to obtain an error between the detected transmitted electric power of the self-station and transmitted electric power set in accordance with a transmitted electric power control bit sent to the self-station from the other station. A buffer unit such as a transmitted electric power deciding part, an error integrating part or the like is provided for preventing the obtained error from greatly changing upon great change of the transmitted electric power when the transmitted electric power is controlled by crossing the threshold value as the detection limit of the transmitted electric power. Thus, an error when the gain of the variable gain amplifier is suppressed.
