System-on-chip interface architecture
A device may include a plurality of data processing engines, a subsystem, and an SoC interface block coupled to the plurality of data processing engines and the subsystem. The SoC interface block may be configured to exchange data between the subsystem and the plurality of data processing engines.
1. A device, comprising:
a plurality of data processing engines;
a subsystem;
a System-on-Chip (SoC) interface block coupled to the plurality of data processing engines and the subsystem, wherein the SoC interface block is configured to exchange data between the subsystem and the plurality of data processing engines;
wherein the SoC interface block includes a plurality of tiles, where each tile is configured to communicate with a subset of the plurality of data processing engines; and
wherein each tile comprises a memory mapped switch configured to provide a first portion of configuration data to at least one neighboring tile and to provide a second portion of the configuration data to at least one of the subset of the plurality of data processing engines.
2. The device of claim 1 , wherein the subsystem includes programmable logic.
3. The device of claim 1 , wherein the subsystem includes a processor configured to execute program code.
4. The device of claim 1 , wherein the subsystem includes at least one of an application-specific integrated circuit or analog/mixed signal circuitry.
5. The device of claim 1 , wherein each tile comprises:
a stream switch configured to provide first data to at least one neighboring tile and to provide second data to at least one of the plurality of data processing engines.
6. The device of claim 1 , wherein each tile comprises:
event broadcast circuitry configured to receive events generated within the tile and events from circuitry external to the tile, wherein the event broadcast circuitry is programmable to provide selected ones of the events to selected destinations.
7. The device of claim 6 , wherein the SoC interface block further comprises:
a control, debug, and trace circuit configured to packetize the selected events and provide the packetized selected events to the subsystem.
8. The device of claim 6 , wherein the SoC interface block further comprises:
an interface that couples the event broadcast circuitry to the subsystem.
