A virtual channel-based computing unit sharing method and system

Abstract

Disclosed is a virtual channel-based operation unit sharing system, comprising: multi-way component requesting ends, each way of the multi-way component requesting ends independently sending a request to an arbiter that has a certificate; the arbiter that has the certificate, which arbitrates the request from the multi-way component requesting ends, assigns an authority to one way component request among the multi-way component requesting ends, and sends an operand of the way component request to an operation unit; the operation unit, which provides an operation result to a distributor; the distributor without a handshake, which distributes the operation result according to a distribution destination ID, and provides same to a corresponding one way component receiving FIFO among multi-way component receiving FIFOs; the multi-way component receiving FIFOs, which are in one-to-one correspondence with the multi-way component requesting ends; multi-way component receiving ends, which are in one-to-one correspondence with the multi-way component receiving FIFOs, wherein one way component receiving end among the multi-way component receiving ends acquires the operation result from a corresponding component receiving FIFO; and a certificate return channel, which separately connects an output end of each way component receiving FIFO to the arbiter that has the certificate.

Description

technical field [0001] The invention relates to the field of computers, in particular to a virtual channel-based computing unit sharing method and system. Background technique [0002] At present, the pipeline operation unit (such as multiplier and divider) in the circuit occupies a lot of resources, and the operation is not performed all the time, so in some occasions, it is hoped that the operation unit can be shared by multiple components through time division multiplexing. The processing time of the arithmetic unit is divided into several time slices by means of time division multiplexing, and these time slots are allocated to multiple components for use. At present, the common solution is to arbitrate multiple inputs, select one to enter the computing unit, and then distribute the results. [0003] figure 1 An example of time-division multiplexing of an existing pipeline operation unit is shown. Such as figure 1 As shown, in the arithmetic unit time-division multipl...

Problems solved by technology

[0006] Aiming at the problem that the operation efficiency is not high due to the inability of other components to perform operations or receive operation results smoothly after data blockage occurs in one of the components in the time-division multiplexing system of the existing operation unit, an embodiment of the present invention provides a virtual channel-based computing unit sharing system, including:
