When CNF receives a pixel data from RSZ, it asserts acknowledge signal. The acknowledge and data receive can be at the same clock, allowing 1pix/cycle transfer. When CNF sends a pixel back to RSZ, it raises req signal on the same clock cycle as the data. RSZ raises ACK signal when it receives the data. Req and Ack can be at the same clock to enable 1 pix/cycle transfer.
Signal | Direction (from RSZ) | Description | Format |
---|---|---|---|
RZAtoCNFA_DOUT | OUT | RZA to CNFA data | 8bit (Cb or Cr per cycle) |
RZAtoCNFA_ACK | OUT | Acknowledge signal of the data from RZA to CNFA | 1 bit. 1 cycle active high pulse |
RZAtoCNFA_REQ | IN | Request signal of the data from RZA to CNFA | |
CNFAtoRZA_DOUT | IN | CNFA to RZA data | 8bit (Cb or Cr per cycle) |
CNFAtoRZA_REQ | IN | Request signal of the data from CNFA to RZA | 1 bit. 1 cycle active high pulse |
CNFAtoRZA_ACK | OUT | Acknowledge signal of the data from RZA to CNFA | 1 bit. 1 cycle active high pulse |
CNFA_HE | IN | Line End signal from CNFA to RZA | 1 bit. 1 cycle active high pulse |
CNFA_VE | IN | Frame End signal from CNFA to RZA | 1 bit. 1 cycle active high pulse |
The following configuration are sent to CNF from ISP-Top (ISP6_SYS3)
