Abstract: Disclosed herein a hydraulic pressure supply apparatus of an electronic brake system includes a motor coupled to a modulator block having a flow path and a valve for adjusting braking hydraulic pressure therein, the motor having a stator and a rotor disposed to be spaced apart from an inner circumferential surface of the stator; a first gear configured to receive a rotational force from the rotor and rotating together with the rotor; a second gear provided with a piston on one side thereof and concentrically connected with the first gear in a ball screw manner to convert a rotational motion of the first gear into a linear motion; and an anti-rotation unit configured to prevent the second gear from rotating together with the first gear.

Abstract: An ATM cell demultiplexing control apparatus comprising an ATM switch interface circuit for performing an interface function with an ATM switch link and outputting ATM cell data received from the ATM switch link and a start signal, a register circuit being enabled in response to the start signal from the ATM switch interface circuit, the register circuit shifting the ATM cell data received from the ATM switch interface circuit to extract a virtual path indicator therefrom and outputting the extracted virtual path indicator and the received ATM cell data, a memory for storing a virtual path indicator table therein and outputting information listed in the stored virtual path indicator table as a processor routing bit map in response to the virtual path indicator from the register circuit, a local processor for updating the virtual path indicator table stored in the memory, a processor cell transmitter for outputting a reception FIFO selection signal in response to the processor routing bit map from the memory t
