| 20080306717 | COOPERATIVE SIMULATION SYSTEM - A program cooperative system (cooperative simulation system), including a number of application programs, can easily modify the combination of application programs to be used according to purpose and realizes excellent throughput by comprising a database memory server memorizing and relaying data; a plurality of simulation tools each of which includes a cooperative module for writing data into and reading data from the database memory server; and a administrating unit setting the database memory server and the plurality of simulation tools and administrating operations performed by the database memory server and the plurality of simulation tools, wherein simulation is executed by the plurality of simulation tools in cooperation with one another. Consequently, the cooperation can be established at the same speed as a memory access speed. | 12-11-2008 |
| 20080303702 | A/D converter - An A/D converter capable of generating an interrupt for requesting a control circuit to read the results of A/D conversion, in desired timing. Analog signals input from channels selected by a channel-selecting section are input to an A/D conversion section, and are sequentially A/D-converted. The results of A/D conversion are sequentially stored in different stages of a FIFO. A stage number-counting section counts the number of the stages of the FIFO where the results of A/D conversion are stored. An interrupt signal-delivering section outputs an interrupt signal for requesting a CPU to read the results of A/D conversion when the number of stages counted by the stage number-counting section is equal to an interrupt-generating stage number set by an interrupt-generating stage number-setting section. | 12-11-2008 |
| 20080218214 | SEMICONDUCTOR OUTPUT CIRCUIT, EXTERNAL OUTPUT SIGNAL GENERATION METHOD, AND SEMICONDUCTOR DEVICE - A semiconductor output circuit, an external output signal generation method and a semiconductor device that suppress variation in an external output signal caused by a decrease in power supply voltage. An output section changes electric potential of an external output signal EB according to a change in electric potential of an internal input signal A from ground to VDD or from VDD to the ground. A differential section outputs an output signal corresponding to the external output signal EB and a predetermined reference signal VREF. The differential section functions as a voltage follower so that the electric potential of the external output signal EB will correspond to the predetermined reference signal VREF. As a result, variation in output voltage VOL at a low voltage side of the external output signal EB is suppressed. | 09-11-2008 |
