Claims

Claim

A computing system containing N processing units and N line arbiters, inputs and outputs of the control data addresses of all processing units are interconnected via the same system main line, characterized in that, in order to increase system performance by providing direct communication between any two processing units system, a system arbiter block is introduced into it, consisting of a polling node, an AND element, an NOT element, a decoder and a trigger, while the outputs are the request line and the code number of the processing block K-th [K = 1 , ..., О {the processing unit is connected to the inputs of the K-th arbiter of the line with the same name, the outputs of the System request for the line, System confirmation of the request for the line, Interrupt request and; Connecting the trunk of which is connected to the inputs of the K-processing block with the same name, the outputs for enabling capture of the trunk of the processing block are connected to the installation input in the trigger О,; the direct output of which is connected to the confirmation inputs of the capture of the trunk of all the arbitrators of the trunk, the inputs of which are connected to the inverse output of the trigger, the outputs of the Inter-machine request of the trunk of all arbitrators are connected to the installation input of 1 trigger and the input of the element NOT, the outputs of Ko ;; the numbers of the processing unit of all arbitrators are connected to the input of the decoder, the outputs from the first to the Nth of which are connected to the inputs respectively of the first processing unit, the output of the And element is connected to the clock input of the polling node, the outputs from the first to the Nth of which are connected to the polling inputs of the arbiters from the first to the Nth ₍ respectively.
