Abstract: A light emitting device includes a substrate and a light emitting body. The light emitting body includes a plurality of light emitting elements and an insulating body in which the plurality of light emitting elements is embedded except for a light emitting surface of the plurality of light emitting elements. The plurality of light emitting elements is formed from a singulated compound semiconductor layer and is arranged in a row direction and a column direction. The substrate includes a drive circuit, a first terminal, and a second terminal and is joined to the light emitting body. The drive circuit drives the plurality of light emitting elements. The first terminal and the second terminal electrically couple the drive circuit and the plurality of light emitting elements to each other.

Abstract: A system for developing the preceding logic to be implemented in a built-in microcomputer that is used while being incorporated in an electronic control unit. The system includes: a motherboard having a first CPU, a first memory, and a first interface via which the motherboard communicates with the outside, interconnected over a first internal bus; a core board having a second CPU, a second memory, quasi microcomputer peripheral devices, which simulate by software the peripheral devices of a microcomputer, and a second interface via which the core board communicates with the outside, interconnected over a second internal bus; and a PCI bus that links the motherboard and the core board. The development system is substituted for the built-in microcomputer in order to implement the preceding logic.

Abstract: Provided is a logic development system that can ensure the capability of a CPU required for preceding logic, guarantee reliable communication of input/output information, and improve the throughput of the CPU. A logic development system for a built-in microcomputer employed in an electronic control unit (ECU) comprises: a motherboard that accommodates an application facility and a communication facility; a core board that accommodates quasi microcomputer peripheral devices, a, computing facility, and a communication facility and that is connected to the motherboard over a PCI bus; and an interface board that includes circuits equivalent to the hardware of the ECU and that is connected to the core board. The communication facility on the motherboard and each of the quasi microcomputer peripheral devices on the core board transfer data directly to or from each other over the PCI bus linking them.

Abstract: Provided is a system for developing the preceding logic to be implemented in a built-in microcomputer that is used while being incorporated in an electronic control unit. The system has a CPU whose capability is good enough to implement the preceding logic.

Abstract: Provided is a system for developing the preceding logic to be implemented in a built-in microcomputer that is used while being incorporated in an electronic control unit. The system has a CPU whose capability is good enough to implement the preceding logic, provides the same assortment of resources as the one to be included in a preceding system, and permits short-term development of a built-in microcomputer that can communicate I/O information reliably and whose CPU enjoys an improved throughput.
