psq_l

Paired Single Quantized Load

psq_l FRT, D(RA), W, I

Loads a paired single from memory (Embedded/Legacy).

Details

Loads a pair of single-precision floating-point values from memory into an FPR, with optional quantization/scaling applied. The W field controls element width, and the I field specifies the scale factor applied during load. This is a legacy VMX/AltiVec instruction primarily found on embedded PowerPC implementations.

Pseudocode Operation

EA ← (RA = 0 ? 0 : GPR[RA]) + D
data ← [EA] (quantized width W, scale I)
FPR[FRT] ← float32_pair(data)

Example

psq_l f1, 0(r4), 0, 0
