MIN Cb Value Register

Indirect (Read Only) Register Index 0x0AF

The MIN Cb Value register lets the host or DSP read the minimum pixel value for the Cb component in the unprocessed data.

The Host reads these values through the Host Interface.

[15:0]

Minimum Cb, MNCB[15:0], 16-bit component pixel value (undefined at reset)

[31:0]

Reserved (always read zero)

MAX Cb Value Register

Indirect (Read Only) Register Index 0x0B0

The MAX Cb Value register lets the host or DSP read the maximum pixel value for the Cb component in the unprocessed data.

The Host reads these values through the Host Interface.

[15:0]

Maximum Cb, MXCB[15:0].16-bit component pixel value (undefined at reset)

[31:0]

Reserved (always read zero)

MIN Cr Value Register

Indirect (Read Only) Register Index 0x0B1

The MIN Cr Value register lets the host or DSP read the minimum pixel value for the Cr component in the unprocessed data.

The Host reads these values through the Host Interface.

[15:0]

Minimum Cr, MNCR[15:0]. 16-bit component pixel value (undefined at reset)

[31:0]

Reserved (always read zero)

MAX Cr Value Register

Indirect (Read Only) Register Index 0x0B2

The MAX Cr Value register lets the host or DSP read the maximum pixel value for the Cr component in the unprocessed data.

The Host reads these values through the Host Interface.

[15:0]

Maximum Cr, MXCR[15:0]. 16-bit component pixel value (undefined at reset)

[31:0]

Reserved (always read zero)

Bin Width and Reciprocal Bin Width Registers

Indirect (Read/Write) Register Index 0x0100-0x0153

The RBW and BW values are calculated by the host or DSP from data in the Sum of Squares [0-41], Sum of Value, MIN Value, and

MAX Value registers; then are written to RBW and BW registers during encode mode to control the quantizer. The Host writes

these values through the Host Interface.

These registers contain a 16-bit interleaved table of alternating RBW/BW (RBW-even addresses and BW-odd addresses) values

as indexed on writes by address register. Bin Widths are 8.8, unsigned, 16-bit, fixed-point values. Reciprocal Bin Widths are

6.10, unsigned, 16-bit, fixed-point values. Operation of this register is controlled by the host driver or the DSP (84 total entries)

(undefined at reset).
