Tightly-coupled, loosely connected distributed systems can be implemented more energy efficient and optimized for computational overhead via multi-protocol heterogeneous packet-based transport. When receiving a plurality of packets from a root complex where contents of each packet from the plurality of packets organized in accordance with a first protocol, a sequence number is added to each packet and a packet type is identified. Every packet in the first plurality of packets is encapsulated into at least one packet organized in accordance with a second protocol to form a second plurality of packets organized in accordance with the second protocol. All the packets from the second plurality of packets can be handled via Direct Memory Access. A write-only communication scheme can be implemented using doorbell and command registers for more efficient data reading and writing in distributed systems.

Deterministic real time multi protocol heterogeneous packet based transport
Deterministic real-time multi-protocol heterogeneous packet-based transport is achieved by traffic shaping. When receiving a plurality of packets from a root complex where contents of each packet from the plurality of packets organized in accordance with a first protocol, a sequence number is added to each packet and a packet type is identified. Every packet in the first plurality of packets is encapsulated into at least one packet organized in accordance with a second protocol to form a second plurality of packets organized in accordance with the second protocol. All the packets from the second plurality of packets pass traffic scheduling or traffic shaping prior being sent via a plurality of connections to avoid burstiness and to achieve bounded transport latency in the plurality of connections, thereby providing deterministic real-time behavior in distributed systems.

Configuration information is generated for a configurable mixed-signal system. Analog requirements for operating the configurable mixed-signal system are gathered. A simulation model of a delta-sigma modulator is received. A simulation based on the simulation model of the delta-sigma modulator is performed to obtain parameter settings for the delta-sigma modulator.
