Example 2: Register Move – PEy Explicit Register
For this instruction, the DSP is operating in SIMD mode, a register in the
PEy data register file is the explicit register and
address in internal memory. The data movement resulting from the evalu-
ation of the conditional test in the PEx and PEy processing elements is
shown in Table
IF EQ DM(I0,M0) = S2;

Example 3: Register-to-Memory Move – PEx Explicit Register
For the following instructions, the DSP is operating in SIMD mode and
registers in the PEx data register file are used as the 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 = R2;
IF EQ PX1 = R2;
IF EQ USTAT1 = R2;
