14. The system of claim 13 , wherein the first electronic device comprises a network processing unit (NPU) and the second electronic device comprises a knowledge based processor (KBP).
13. A system, comprising: a first electronic device having a request transmitter for transmitting periodic request packets in accordance with a serial protocol and a receiver for receiving response packets; a serial link having one end coupled to the first electronic device to route the request packets; and a second electronic device having a receiver circuit coupled to a second end of the serial link to receive the request packets and a response transmitter for transmitting the response packets to the first electronic device; wherein the first electronic device and the second electronic device cooperate to form respective request and response paths having associated request and response path latencies; wherein the response path latency is based on the request path latency; and wherein the first electronic device includes queuing logic to assign processing timeslots based on a deterministic latency.
