    Abstract: A computer processor comprises: a fetch unit that reads and writes instructions and data, a register file including a plurality of registers, which includes a general-purpose register and a special register, an arithmetic logic unit that performs computational processing, a decoder/controller that interprets the instructions and generates a control signal, a symmetric network interface that includes a master interface and a slave interface and that is connected to an on-chip network; and a service controller that receives a service request from the external source through the on-chip network and the symmetric network interface, that communicates with the decoder/controller to send and receive a state of the service request and a state of the computer processor, and that copies an instruction address of a subroutine for executing the service request to a program counter to perform an operation of a designated code when the decoder/controller determines execution of the service request.

    Abstract: A lane detection and lane departure determining device and method are provided. The lane detection device includes a first Region of Interest (ROI) setting unit configured to set a rectangular ROI from an input image which is a road image, a second ROI setting unit configured to set a Λ-ROI having distorted trapezoidal shape from the rectangular ROI, and a lane detection unit configured to detect the lane including a left and right lane marking in the Λ-ROI. The second ROI setting unit is configured to calculate a merged first line segment through a merging process, obtains a left and right second line segment by scanning brightness, and determines the left and right second line segment as a temporary left and right lane marking when a preset condition is satisfied. The Λ-ROI is determined by changing a slope of the temporary left and right lane marking in a predetermined range.
