prism_single_data_receiver

prism_single_data_receiver validates a complete NumberGroup DATA frame before it advances interval ownership or emits arithmetic work.

Contracts

  • Ingress AXI stream: accepts rank frames with explicit tkeep and tlast.
  • Installed context: binds logical endpoints, contributor IDs, packet limits, formats and the current operation generation.
  • Tile output: carries consecutive values with their global first position; tile boundaries do not change the arithmetic identity.

Contract behavior

  • Checks descriptor counts, payload length, padding, frame bounds and binding before the validated reader can issue values.
  • Tracks interval coverage and LAST per contributor; overlapping intervals do not apply a second contribution.
  • Derives the active element window from the configured MTU. Duplicate or overlapping element intervals cannot issue arithmetic twice. DATA retransmission and PROGRESS acknowledgment are outside the SINGLE contract.
