Abstract

An electronic device, comprising: a first component configured to transmit a first set of data to a second component by providing a first memory request specifying the first set of data for and an input memory address, and a transaction tracking unit coupled to a first transport interface, the transaction tracking unit configured to: receive the first memory request; transmit a second memory request that specifies at least a first portion of the first set of data, via the first transport interface, to the second component; receive a response to the second memory request from the second component; determine that the response corresponds to the second memory request; and provide, to the first component, an output response based on the received response to the second memory request.

Claims20

Dependent claims

A circuit device comprising:

a requesting component configured to provide a transaction that specifies a set of data and includes destination information;
a first communication circuit coupled to the requesting component, the first communication circuit including a transaction mapper;
and
a set of interfaces configured to couple the first communication circuit to a second communication circuit, wherein:
the first communication circuit is configured to:
receive the transaction;
based on the destination information of the transaction and a mapping in the transaction mapper, determine an operating mode for transmitting the set of data, from among multiple operating modes for transmitting the set of data, and based on the determined operating mode for transmitting the set of data, determine a subset of set of interfaces over which to transmit the set of data;
and
cause the set of data to be transmitted to the second communication circuit over the subset of the set of interfaces.
