Abstract: PURPOSE:To obtain a programmable delay circuit in which a test time is reduced by adopting a select circuit configuration for delay gates of N-stages of delay circuits and adding a selection circuit selecting one of the delay gates to the select circuit. CONSTITUTION:A decoder 6 outputs select signals Sel#0-#2n-1 with respect to N-sets of output circuits 21-2N based on delay setting input data SELECT in n-bit (2 =N) to select any one of N-sets of the output circuits thereby setting a delay amt. An H level signal as a circuit test signal TD 2 is given to a shift register 7 and k-sets of clock pulses TC are given to the shift register 7 and the data SELECT to select a path of Sel # are given to the decoder 6. As a result, the shift register 7 selects a delay gate 1k+1 (Gate #k) and the decoder 6 selects the output circuit 2k+1 Then test signals TD1, TD1B being at H and L levels respectively are received by the shift register 7 and whether or not delay outputs OUT, OUTB are led out from a delay extract circuit 5 is tested.

Abstract: PURPOSE:To provide a pulse width modulation circuit capable of expanding an operation frequency range, coping with the plural pieces of resolution and reducing a cost. CONSTITUTION:By using an OR gate 2, first and second delay circuits 3 and 4 and a gate 5, the loop route of clock pulses is formed so as to let the clock pulses pass through the first and second delay circuits 3 and 4 only for the number of times corresponding to an operation frequency. By performing the opening/closing control of the gates 5, 18, 19 and 21 corresponding to enable signals S14, S15 and S16, the timing of the rise and fall of output pulses PWMOUT is generated. Thus, pulses can be generated even in the case of a lower frequency.

Abstract: PURPOSE:To expand variable delay time width by generating a ramp waveform based on the frequency division output of an input signal, and obtaining delay time by slicing it by a reference voltage. CONSTITUTION:Frequency division signals SA1-SD1 with long period are generated for an input digital signal CLK by a frequency division circuit 11. The ramp waveforms SA2-SD2 can be obtained from the signals by ramp waveform generation circuits 14-17, and they are compared with a threshold value set from the outside by comparators 22-25, thereby, output SA3-SD3 can be obtained. Timing pulses SA4-SD4 in accordance with inversion time at that time are generated at pulse generation circuits 26-28. A delay signal Sout can be formed at a delay signal formation circuit 30 based on the timing pulses SA4-SD4.

Abstract: PROBLEM TO BE SOLVED: To provide a communication device and a communication method which can reduce a processing burden of a host and a network load.
SOLUTION: A packet parser 13 is provided between a network interface card 12 and the host 11 (a reception processing part). The packet parser 13 executes header analysis of the received packet and it determines the protocol of the packet. When the determined result is an important packet, the packet parser 13 notifies the host 11 of the reception (interruption) unconditionally, that is to say, so as to preferentially execute reception processing. When it is an un-important packet, interruption is executed, for example, after a data amount exceeds a setting value. Also, when it is a real time stream packet, the packet parser 13 directly transfers it to a Codec not to the host.

Abstract: PROBLEM TO BE SOLVED: To transmit packets with a high throughput and high reliability. SOLUTION: A communication unit 1A forms a packet TA1 whose packet length is longest, transmits it to a communication unit 1B. When no acknowledgment ACK is returned from the communication unit 1B, the communication unit 1A forms a packet TA2 whose packet length is decreases and transmits it to the communication unit 1B. When no ACK with respect to the packet TA2 is returned, the communication unit 1A forms a packet TA3 whose length is furthermore decreased and transmits it to the communication unit 1B. Upon the receipt of a packet TB3 that is an ACK packet from the communication unit 1B, the communication unit 1A forms a packet DA1 with the same packet length as that of the packet TA3 where user data to be sent first are arranged and transmits it to the communication unit 1B. Then the communication unit 1A sequentially arranges the user data to the packet whose length is the same as that of the packet TA3 and transmits the packet to the communication unit 1B.
