Section 4 Instruction Features
4.6.2
Parallel Processing Instructions
Parallel processing instructions are used by the SH-DSP to increase the execution efficiency of
digital signal processing using the DSP unit. They are 32 bits long and four can be processed in
parallel (one ALU operation, one multiplication, and two data transfers).
Parallel processing instructions are divided into two fields, A and B. The data transfer instructions
are defined in field A and the ALU operation instruction and multiplication instruction are defined
in field B. These instructions can be defined independently, processed independently, and can be
executed simultaneously in parallel. Table 4.12 lists the field A parallel data transfer instructions;
figure 4.14 shows the field B ALU operation instructions and multiplication instructions. The field
A instructions are identical to the double data transfer instructions shown in table 4.10.
