Table 5.10 shows the DSP data transfer instructions by category.
Table 5.10 DSP Data Transfer Instruction Categories
The data transfer instructions are divided into two groups, double data transfers and single data
transfers. Double data transfers are combined with DSP operation instructions to create DSP
parallel processing instructions. Parallel processing instructions are 32 bits long and include a
double data transfer instruction in field A. Double data transfers that are not parallel processing
instructions and single data transfer instructions are 16 bits long.
In double data transfers, X memory and Y memory can be accessed simultaneously in parallel.
One instruction is specified each for the respective X and Y memory data accesses. The Ax
pointer is used for accessing X memory; the Ay pointer is used for accessing Y memory. Double
data transfers can only access X and Y memory.
Single data transfers can be accessed from any area. In single data transfers, the Ax pointer and
two other pointers are used as the As pointer.
