Compute in memory architecture that allows flexible floating-point operations

PCT designated stageWO2026178063A1Floating pointOperand
The disclosure describes systems and methods for mixed‑mode, mixed‑precision computation using a configurable compute engine for vector–matrix operations. A processing system selects an operating mode including at least a floating‑point mode or an integer mode for the compute engine. Operand storage and format preprocessing route differently sized element representations through shared lanes. In floating‑point mode, compute circuitry generates a mantissa product and a product exponent, and alignment applies power‑of‑two control through a selection network, including as part of a fused multiply‑accumulate path. Parallel adder trees feed a hierarchical output accumulator sized to the selected precision. Normalization operates at a wider intermediate precision, applies block‑level scaling with dequantization, and, in lower‑precision operation, performs groupwise normalization with an intermediate‑precision combine to preserve a constant compute‑block size. Implementations integrate the compute engine within a memory macro with double buffering or deploy the compute engine as a standalone accelerator.
