Abstract
An accumulator broadcast network is described that permits an accumulator in one core of a multi-core IC to transmit high-precision data to accumulators in multiple cores in parallel. That is, instead of a sending data to local memory and the broadcasting to different cores using shared memory or messaging protocols, the data stored in the accumulator registers can be directly transmitted to other accumulators.
Claims20
An integrated circuit (IC) comprising:
- an array of data processing engines (DPEs), each comprising a core, wherein each of the cores comprises an accumulator;
- and
- an accumulator broadcast network comprising direct core-to-core links that interconnect the accumulators in the cores,
- wherein a first core of the cores is configured to use the accumulator broadcast network to transmit accumulator data to multiple cores in parallel.

A method comprising:
- configuring an accumulator broadcast network in an IC, the IC comprising an array of data processing engines (DPEs), each comprising a core, wherein each of the cores comprises an accumulator, and wherein the accumulator broadcast network comprises direct core-to-core links that interconnect the accumulators in the cores;
- synchronizing a first core of the cores to multiple cores of the cores;
- and
- broadcasting accumulator data from the first core to the multiple cores in parallel using the accumulator broadcast network.
