Transformer/LLM Inference Accelerator

Purpose-built for transformer and LLM inference: systolic compute units with a fused attention engine, high-bandwidth memory, and an MLIR compiler stack so your models map cleanly to the hardware.

Memory bandwidth feeds the PE array; attention runs fused in hardware — not bolted on in software.
Features

Attention, in hardware.

Compute

Systolic GCUs

64×64 systolic arrays with a fused attention engine for transformer workloads.

Memory

HBM3 @ 2 TB/s

On-package SRAM plus HBM3 to keep the arrays fed.

Software

MLIR compiler

FP8 / BF16 / INT8 — models lowered through an MLIR stack.
