    • An apparatus and a method for preventing a glitch in a clock switching circuit are provided to prevent a system error due to a glitch by preventing the generation of the glitch when a switching operation between clocks is performed in the clock switching circuit. A clock selection unit(220) generates a detect change(Detect_change) signal as an input signal for generating a clock gate(Clk_gate) signal and provides the detect change signal to the clock selection unit. A selection signal management unit(200) changes a Muxsel signal to a selection signal by using a clock gate signal, in order to select a clock to be switched. A clock gate unit(210) generates a clock gate signal by gating the received clock and using a value of the detect change signal as an input signal when receiving the detect change signal. The clock gate unit provides the clock gate signal to the selection signal management unit.
    • 提供了一种用于防止时钟切换电路中的毛刺的装置和方法,以防止在时钟切换电路中执行时钟之间的切换操作时通过防止产生毛刺产生的毛刺引起的系统错误。 时钟选择单元(220)产生检测变化(Detect_change)信号作为用于产生时钟门(Clk_gate)信号的输入信号,并将检测改变信号提供给时钟选择单元。 选择信号管理单元(200)通过使用时钟门信号将Muxsel信号改变为选择信号,以选择要切换的时钟。 时钟门单元(210)在接收到检测改变信号时,通过门控接收到的时钟并使用检测改变信号的值作为输入信号来产生时钟门信号。 时钟门单元向选择信号管理单元提供时钟门信号。

    • PURPOSE: An interrupt controller is provided to prevent generating of a glitch and to reduce power consumption. CONSTITUTION: An interrupt controller comprises the parts of: a first interrupt generating circuit(10) that generates a first interrupt, which is synchronized and it changes sleep mode to active mode; a second interrupt generating circuit(20) that generates a second interrupt, which changes sleep mode to active mode by receiving first interrupt source request signal as clock signal; a selecting control circuit(30) that generates selection signal to select a first and second interrupt; a clock generating circuit(40) that generates a first clock signal by receiving selection signal and a second clock signal generated from sleep mode and active mode; a clear circuit(50) that initializes a first and second interrupt source circuit; and a selecting circuit(60) that selects one between a first and a second interrupt, responding selection signal.
