摘要:
A digital signal processor for determining the maximum and minimum values of a plurality of data items wherein operations of an arithmetic logic unit and data memories are controlled by micro-instructions, including a device for decoding specified bits of an operand of the micro-instruction, a device for detecting a value of a condition code which has been designated by an output of the decoding device, and a control device for executing a logical operation between the output of the detection device, which becomes "1" if the value of the condition code is true, and a decoded value of an operation code of the micro-instruction and to generate a control signal for the arithmetic logic unit on the basis of a result of the logical operation.

A processor comprises first and second operation units, a first program memory which contains first microinstructions for controlling the first operation unit and second microinstructions for controlling at least the second operation units, a second program memory which contains microinstructions for controlling the second operation unit, first control means connected to the first program memory for controlling the first operation unit and the second operation unit, and second control means connected to the second program memory for controlling the second operation unit. In a normal mode, all operation units are under control of the first control means and in a multiprogram mode, the first operation unit is under control of the first control means and the second operation unit is under control of the second control means. These two mode operations are selected in accordance with the microinstructions stored in the first or second program memories.

A memory circuit is divided into a plurality of memory blocks, and an address register and a delay register are disposed in each memory block. Therefore, a read or write operation and a shifting operation of the address for storing data inside a memory matrix can be realized by a pipeline technique, and hence a memory circuit having a high processing speed is obtained.

An LSI system is disclosed in which a plurality of status registers for indicating the internal status of the system are connected to each other so as to form a hierarchical structure and the contents of each of the remaining status registers other than one status register can be transferred to an output register through a bus, to make it possible to provide additional status registers in the system without increasing the number of address signals used and the number of pins connected to external address signal lines.

A high-speed multiplier adapted to VLSI with a regularly arranged structure having a reduced number of addition stages. There is provided a carry save adder circuit wherein a time difference is imparted to signals input to full adders, in order to eliminate extra wait time in the signal propagation. That is, a carry signal of a full adder of two stages over is input with a speed increase of 1/2T.sub.FA.

When a guidance function is actuated in a guidance method in a computer system, icons displayed on a screen are picked up to form their list. When a user designates an icon requiring the guidance, the guidance scenario corresponding to the designated icon is picked up, and icons required to execute the guidance scenario is allotted to the guidance scenario from the list. Thereafter, the guidance scenario is demonstrated using the allotted icons.
摘要:
A multiprocessor system includes processor units connected physically in one-dimensional fashion along a ring bus located at the node of each processor element and associated local memory, so that various system operating modes are possible. The ring bus is used for inter-processor data transfer, with the address and read/write signals to each local memory being supplied from the processor element (by the program). Sychronization between the data flow on the ring bus and the processor operation is made automatic by the innovated method of inter-processor connection, which includes flag latches in the ring bus, whereby the system accomplishes extremely high-speed processing.

A load on the shins when a knee airbag is deployed by inflating in a state in which the knees of an occupant are proximate to an airbag door or suchlike is moderated. Inside a knee airbag, an upper tether and a lower tether are disposed to sandwich an inflator from above and below. First opening portions and second opening portions for letting gas flow through up and down are alternatingly formed in the upper tether and the lower tether. The second opening portions are formed as circular holes with smaller diameters than the first opening portions. The second opening portions are disposed at positions opposing the knees of a small occupant in a sitting state.

An air bag door is developed quickly even if the clearance between the grab door outer and the knee of a crew or passenger is narrow when a tier type air bag door is employed in a knee air bag device for vehicle. A fracture portion (50) consisting of a lateral fracture portion (50A) and longitudinal fracture portions (50B, 50C) is formed in the grab door outer general portion (24A). Thus, an air bag door (52) consisting of total six doors, i.e. an upper central air bag door (52A), an upper left side air bag door (52B), an upper right side air bag door (52C), a lower central air bag door (52D), a lower left side air bag door (52E), and a lower right side air bag door (52F), is formed. Even if both knees of the crewman or passenger of a small-sized build are arranged in proximity to or in contact with the lower left side air bag door (52E) and the lower right side air bag door (52F), the lower central air bag door (52D) opens smoothly between both the knees in addition to the upper side air bag doors in the initial stage of development of the air bag door (52).

In a knee airbag device for a vehicle, which has upper and lower tethers that extend in a vehicle width direction and regulate a bag thickness of an airbag, and in which gas from an inflator is supplied between the upper and lower tethers, it is aimed to make a flow of the gas toward an upper portion and a lower portion from between the upper and lower tethers at the inside of the knee airbag smoother, and to improve deployability of the knee airbag in a vehicle vertical direction.Upper and lower tethers 16 and 18 are arranged to be separated from each other in the vehicle vertical direction and are formed so that a vertical clearance therebetween increases approaching both vehicle width direction end portions 16A and 18A thereof. When the gas is supplied between the upper and lower tethers 16 and 18, the gas spreads to both vehicle width direction sides along the tethers 16 and 18 and smoothly moves around into an upper portion 14A and a lower portion 14B of a knee airbag 14 from both of the end portions 16A and 18A of the tethers 16 and 18.
