Figure SCU (Sensor Control Unit)-58 Decimation Partition Data Path
・Preprocessing can be performed to the 1, 2, or 3 axis data of the signed 16 bit.
・The data after preprocessing can be sent through three lines of Decimeters and one bypass path.
・Afterwards, Dynamic Range adjustment can be applied separately to the four lines of data.
・And then, the Math Function can be assigned.
Figure SCU (Sensor Control Unit)-59 Normal Sensor Partition Data Path
・Preprocessing can be performed to the 1, 2, or 3 axis data of the signed 16bit.
・Afterwards, the Math Function can be assigned.
The Math Function processing can be inserted in up to three paths among the total of 16 paths in the
MATH_PROC (four paths per Decimation Partition Data Path x two lines, 1 path per Normal Sensor Partition
Data Path x eight lines). In the Decimation Partition Data Path example in Figure SCU (Sensor Control Unit)-58,
the Math Function is inserted only in the Decim 0-3 lines, and the Dynamic Range adjustment (DR) output is
directly connected to the direct connection/Decim 0-1/Decim 0-2 lines.
3.9.7.1 Preprocessing
The following functions can be executed for all MATH_PROC paths according to the values set in the registers.
(1) Signed data/unsigned data conversion
(2) Offset addition
(3) Gain multiplication
These processes are called Preprocessing and the data flow is shown in Figure SCU (Sensor Control Unit)-60.
