    摘要: A first processor, a second processor, a memory and a clock supply unit are integrated together on a single chip. The first processor operates synchronously with a first internal clock signal. The second processor operates synchronously with a second internal clock signal. The memory operates synchronously with a third internal clock signal. The clock supply unit generates three clock signals, which are in phase with each other, from an external clock signal and supplies those clock signals as the first, second and third internal clock signals. The first and second processors share the memory via a data bus. Each of the processors has an internal reset signal.

    摘要: In a circuit block 110 to be an object of power-off, voltage detecting circuits 130 and 134 are disposed near power supply terminals 140 and 142, respectively, and voltage detecting circuits 132 and 136 are disposed at given positions far from the terminals 140 and 142, respectively, on power lines 141 and 143 of two electric-supply systems. The voltage detecting circuits are each made of MOS transistors only. At turning on the power from a power supply circuit 150 again, after all the voltage detecting circuits have detected arrival of power-supply voltages at a predetermined potential, a reset signal generating circuit 160 stops the input of a reset signal to the circuit block 110. Accordingly, since the reset state is stopped after the arrival of the power-supply voltages at the predetermined voltage, a semiconductor integrated circuit is initialized normally. This provides a semiconductor integrated circuit capable of generating a power-on reset signal appropriately.

    摘要: A coding apparatus includes shift register, input register and logical operation section. The shift register performs bit shifting on an input bit sequence and stores one bit of the input bit sequence after another. The input register stores coefficients of terms on respective orders of a generator polynomial. The logical operation section obtains logical products of the respective bits stored on the shift register and associated bits stored on the input register and a logical product of each one bit input to the shift register and an associated bit stored on the input register so that the earlier a bit of the input bit sequence was input, the higher-order one of the coefficients in the terms of the polynomial the input bit is associated with. Next, the logical operation section derives an exclusive logical sum of the products and then outputs the sum as a bit of a code sequence.

    摘要: A plurality of logic element groups LEG11 to LEG33 respectively include at least one logic element as a component of a reconfigurable semiconductor integrated circuit. Between any logic element groups engaging in data transmission/reception, e.g., LEG11 and LEG12, clock out terminal and clock in terminal are connected via a line while data out terminal and data in terminal are connected via a delay element 101. The logic element groups LEG11 to LEG33 are therefore independent of one another in terms of timing design. Thus, if redesign is necessary for a semiconductor integrated circuit completed with a plurality of logic element groups, only a new circuit may be designed and connected to an existing circuit, or an unnecessary logic element group may just be removed, to complete a new semiconductor integrated circuit.
