摘要:
When an instruction decoder decodes an instruction code included in packet data, a copy flag and copy number information are provided to a self-synchronous transfer control circuit. In the self-synchronous transfer control circuit, when a data transfer enabling signal is applied from a C element in a subsequent stage, a node number manipulation circuit manipulates a node number to make copies such that packets can be distinguished from each other, and then data is transferred from a pipeline register to a pipeline register in a subsequent stage.

A data-driven type information processing apparatus includes at least a paired data generating unit, a memory control unit, and data memory. The memory control unit includes a pipeline register receiving a data packet output from the paired data generating unit, including a page address, a set value for setting an effective bit and data, and an address generating unit for generating an address for accessing the data memory by retrieving effective data from the data included in the data packet based on the set value and attaching the page address included in the data packet to the retrieved effective data.

A data packet, having a flag for determination of its processing content, a tag field and a data field, is sequentially transferred between pipeline registers according to pulses from C elements. A determination is made as to whether the tag field of the data packet includes information identical to that pre-stored in a tag field of a register within a processing content determination unit. Based on the determination result, the data packet is processed according to the information stored in a processing content determination field of the register.
摘要:
An input port receives input data X, generates input packets by adding generation numbers and node numbers indicative of prescribed destinations, in the order of reception, and in addition, generates a data packet from a separately input clock signal. The input data packet is written to an image memory using the generation number in the packet as an address signal, or read from the image memory using the generation number in the data packet as an address signal. Operation is performed in accordance with the input data packet or the data packet read from the image memory by a memory interface, and the processed data packet is output to the outside of a data driven engine, a memory interface or a data driven type processor.

A C element controls a pipeline register and successively transfers data packets. When a dead-lock state occurs, a data packet in the pipeline register is erased by a master reset signal, a host transfer flag operating circuit overwrites a data packet in the pipeline register so that it has a host transfer flag at the “H” level, and thereafter, when the host transfer flag is detected in the subsequent stage, the data packet is transferred to the host.

A data driven type processing device has an error diffusion computing unit built therein. An error holding register is provided within the error diffusion computing unit, and is used to successively store and update a value of error information of a pixel that is to be diffused to a neighboring pixel being processed continuously. An error data memory is provided outside the computing unit, and is used to store and update a value of the error information that is to be diffused to another neighboring pixel being processed discontinuously. The error information and the values to be diffused are stored in a packet, and the packet is circulated for operation.

In an LED light bulb, an LED module and a lens are disposed on a fixing stage provided to a housing. The lens has a concave portion at its top end. The concave portion forms a reflecting surface which reflects part of outgoing light from the LED module to (i) first directions perpendicular to a front emission direction of the outgoing light or (ii) second directions leaning to a cap beyond the first directions. Due to diffusion effect of an optical cover, part of the light reflected by the lens is emitted backward (toward the cap). This realizes an LED light bulb that distributes light over an entire circumference and has high output as well as high light output ratio.

Unevenness in brightness of a plane light source is controlled to improve a display quality of a plane light source. An LED module comprising one or a plurality of light source sections with a high brightness peak value and a large light and dark contrast difference, and an LED module comprising one or a plurality of light source sections with a low brightness peak value and a small light and dark contrast difference, are alternately arranged. The one or the plurality of light source sections comprise a white resist arranged on a substrate region around LED, as a reflection material. The light source section with a large brightness peak value and a large light and dark contrast difference, and the light source with a low brightness peak value and a small light and dark contrast difference, are formed by the difference in a reflection rate of the white resist.
