  • Publication number: 20150180784
    Abstract: A bus system (100) for a semiconductor circuit transmits data on a networked bus between a first node and at least one second node via a relay device (250) arranged on the bus. The bus system (100) includes a first bus of a low delay and a second bus of a high delay. The first node generates a plurality of packets by attaching, to the data stored in a buffer (202), information specifying a priority of transmission. The relay device (250) converts a priority based on a priority conversion rule, which is determined based on a transmission delay of the high-delay bus, allocates a buffer of a destination relay device to which each packet is to be sent, based on the converted priority, and sends packets in a descending order. The relay device (250) stores packets in a buffer (252) based on the priority.

  • Publication number: 20150010005
    Abstract: In the bus system, bus interface apparatuses and routers are connected together through packet exchange buses which have been established on the integrated circuit. The bus interface apparatuses are respectively connected to transmission nodes which transmit data of mutually different numbers of bits in one cycle of operation of the bus system. Each of the bus interface apparatuses generates and transmits a packet based on data received from the transmission node connected and header information including size information indicating the number of bits with respect to the transmission node connected. The router analyzes the packet, gets the size information from the header information, determines how to allocate a space in the buffer for storage by reference to the size information gotten, and stores the received packet in the buffer.

  • Patent number: 8929671
    Abstract: An image processing apparatus includes a frame memory, a motion vector detector, a screen edge detector and an interpolation frame generator. The frame memory frame-delays an input signal and outputs the input signal as a delayed input signal. The motion vector detector detects a motion vector between frames based on the input signal and the delayed input signal. The screen edge detector detects a pixel corresponding to a screen edge in the input signal. The interpolation frame generator generates an interpolation frame from the input signal and delayed input signal based on the motion vector and the pixel corresponding to the screen edge. The interpolation frame generator generates the interpolation frame using the pixel corresponding to the screen edge or the pixel inside relative to the pixel corresponding to the screen edge when the motion vector points a pixel outside relative to the pixel corresponding to the screen edge.
