3.5.3 DSP-Type Data Formats
This LSI has several different data formats that depend on the instruction. This section explains
the data formats for DSP type instructions.
Figure 3.8 shows three DSP-type data formats with different binary point positions. A CPU-type
data format with the binary point to the right of bit 0 is also shown for reference.
The DSP-type fixed point data format has the binary point between bit 31 and bit 30. The DSP-
type integer format has the binary point between bit 16 and bit 15. The DSP-type logical format
does not have a binary point. The valid data lengths of the data formats depend on the instruction
and the DSP register.
