Dear All,

Hello.

Refer to DP_CSC_A8_SYNC [10 bit] in IPUx_DP_SCS_SYNC_0 register.

[Q1]

Could you tell me the plus/minus sign, integer part and decimal part in this bits?

9~10 --> plus/minus sign? Please explain the detail.

7~8 --> integer part?

0~6 --> decimal part?

The register detail description wasn't found.

[Q2]

Which is the right calculation round-up or round-off for 4th decimal place?

[Q3] (Confirming)

In case of DP_CSC_A8_SYNC = 0x3EB(0b1111101011), what is the result value at decimal value?

Best Regards,

Keita

For better understanding, refer to the following thread:

Changing IPU Color Space Conversion parameters

and follow the code, referenced there. Also, refer to the whole Section 37.4.9.5 "Color Space Conversion unit - CSC" of the i.MX6DQ Reference Manual Rev.3 document. The descriptions, given there, are correct. All coefficient numbers are represented using two's complement format.
