Technique for scaling the bandwidth of a processing element to match the bandwidth of an interconnect

摘要

A transmitter is configured to scale up a low bandwidth delivered by a first processing element to match a higher bandwidth associated with an interconnect. A receiver is configured to scale down the high bandwidth delivered by the interconnect to match the lower bandwidth associated with a second processing element. The first processing element and the second processing element may thus communicate with one another across the interconnect via the transmitter and the receiver, respectively, despite the bandwidth mismatch between those processing elements and the interconnect.

1. A computer-implemented method for scaling the bandwidth of a processing element to match the bandwidth of an interconnect, the method comprising:
receiving, at a first bandwidth, a first data block from a first processing element, wherein the first processing element operates at the first bandwidth; extracting a first portion of the first data block; inserting discardable values into the first portion of the first data block based on an encoding function associated with a serial mask to generate first expanded data, wherein the serial mask is selected via a negotiation between the first processing element and a second processing element; and transmitting, at a second bandwidth, the first expanded data to the second processing element across the interconnect, wherein the interconnect operates at the second bandwidth.
