Example 4: Register-to-Memory Move – PEy Explicit Register
For the following instructions, the DSP is operating in SIMD mode and
registers in the PEy data register file are used as explicit registers. The data
movement resulting from the evaluation of the conditional test in the PEx
and PEy processing elements is shown in
IF EQ R9 = S2;
IF EQ PX1 = S2;
IF EQ USTAT1 = S2;
