TM STDP adaptor's timing diagram of one time slot. (A) Starting a time window. Pre_aligned is ready at T3 and TW_active will be ready at T8. As the time window is inactive, the delayed Pre_aligned (the red one) will start the time generator at T8 by sending a pulse (TW_start, starts at T9); (B) Increasing weight. The polarity of the time window (TW_polarity) and the local weight (L_rddata) are both read out at T0 and ready at T2. Post_aligned is ready at T3 and TW_active will be ready at T8. The delayed Post_aligned (the red one) will increase L_rddata.
