Data transfer switch for transferring data of an arbitrary length on the basis of transfer destination
First Claim
1. A data transfer switch having a plurality of input accommodation units and a plurality of output accommodation units to transfer data of an arbitrary length input from an arbitrary input accommodation unit to a predetermined output accommodation unit on the basis of transfer destination information, comprising:
- switch control means for selecting one of transfer requests having the same output accommodation unit serving as a transfer destination from all transfer requests output from the input accommodation units, outputting a selector control signal instructing to select data from a transfer source input accommodation unit, as the data for transferring to a transfer destination output accommodation unit, the selector control signal designating to select data from the transfer source input accommodation unit, and outputting a transfer permission to the transfer source input accommodation unit; and
selector switch means for selecting, on the basis of the selector control signal output from said switch control means, one of data output from the input accommodation units as data to be transferred to each output accommodation unit, connecting the transfer source input accommodation unit to the transfer destination output accommodation unit in a one-to-one correspondence, and transferring the data from the transfer source input accommodation unit to the transfer destination output accommodation unit in accordance with the transfer permission in one direction, said selector switch means having no memory device and having a distributor unit and a plurality of selector sections.

Abstract
A data transfer switch includes a switch controller and a selector switch unit. The switch controller selects one of transfer requests having the same output accommodation unit serving as a transfer destination from all transfer requests output from the input accommodation units, outputs a selector control signal, as data to be transferred to a transfer destination output accommodation unit, the selector control signal designating to select data from a transfer source input accommodation unit, and outputs a transfer permission to the transfer source input accommodation unit. The selector switch unit selects, on the basis of the selector control signal output from the switch controller, one of data output from the input accommodation units as data to be transferred to each output accommodation unit, connects the transfer source input accommodation unit to the transfer destination output accommodation unit in a one-to-one correspondence, and transfers the data from the transfer source input accommodation unit to the transfer destination output accommodation unit in accordance with the transfer permission in one direction.

7. A data transfer switch having a plurality of input accommodation units and a plurality of output accommodation units to transfer data of an arbitrary length input from an arbitrary input accommodation unit to a predetermined output accommodation unit on the basis of transfer destination information,
the plurality of input accommodation units being adapted to individually output transfer requests for a plurality of data having different transfer destinations and output corresponding data in response to transfer permissions corresponding to the transfer requests, comprising: -
switch control means for selecting one of transfer requests having the same output accommodation unit as a transfer destination, the transfer requests being output from input accommodation units to which transfer permissions are not notified and being selected from all transfer requests from the input accommodation units, for outputting a selector control signal instructing to select data from a transfer source input accommodation unit, as the data for transferring to a transfer destination output accommodation unit, the selector control signal designating to select data from the transfer source input accommodation unit to the transfer destination output accommodation unit, and for outputting a transfer permission to the transfer source input accommodation unit in a manner where a plurality of transfer permissions will not be given simultaneously to the transfer source input accommodation unit; and selector switch means for selecting any one of the data output from the input accommodation units as data to be transferred to each output accommodation unit, on the basis of the selector control signal from said switch control means, connecting the transfer source input accommodation unit to the transfer destination output accommodation unit in a one-to-one correspondence in response to the transfer permission, and transferring the data output from the transfer source input accommodation unit to the transfer destination output accommodation unit in one direction. - View Dependent Claims (8, 9)
