Abstract: A multiple channel memory controller includes: an application adaptor that transfers a command or data received from a host to the outside, and transfers a response associated with the transferred command or data to the host; a plurality of memory adaptors that are respectively connected one-to-one to a plurality of memory devices to form corresponding physical channels; and a virtual channel controller that is located between the application adaptor and the plurality of memory adaptors, and transfers the command or data to at least one physical channel allocated to the virtual channel.

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.
