Tmac

Tmac Function: Beacon generation.

(BM: central beacon,

proxy BM: proxy beacon,

associated and authenticated STAs: discover beacon).

Long SOF MPDU generation. Sound MPDU generation. Generate RTS if necessary. Fetch CTS, SACK, or Sound ACK from RMAC.

Tmac architecture

Tmac_mpdu

Generate various types of mpdu

module tmac_fsm(); 負責控制 tmac state的轉換，並且產生控制訊號 .module mpdu_gen_fsm();

控制組成mpdu所需要經過的步驟 .module fc_gen();產生 1901 MPDU 的 Frame Control部分 (FCCS: CRC-24)，並根據目前 state 決定產生哪種

MPDU.module pb_gen();根據 state去讀取 PBH,PBB/beacon payload/generate padding
