Hardware link (de)compression IP for die-to-die, chip-to-chip, and DRAM interfaces
Expands effective bandwidth across links and memory interfaces with deterministic, data-independent latency, fully pipelined to sustain line rate
Overview
Hardware link (de)compression IP for streaming bandwidth expansion across die-to-die, chip-to-chip, and DRAM interfaces. Fully pipelined to sustain line rate, with deterministic, data-independent latency.
ZeroStream is a hardware compression and decompression IP block that expands effective memory bandwidth for AI accelerators. It compresses data in real time as it moves across a link or memory interface, so more useful data is delivered per cycle without changing the host software or retraining models.
Why it matters
Compression ratio translates directly into throughput on bandwidth-bound workloads. For LLM decode, which is memory bound, more effective bandwidth means more tokens per second from the same silicon and the same memory.
Software library included
The IP solution ships with a software library that adapts the encoding to different LLM models and data types for higher compression efficiency and optimal bandwidth. The library is transparent to the user and the system.
Key specifications
Headline characteristics below. Area, gate count, and cycle-level latency figures are configuration dependent.
| Target data | Any data. Examples: weights, activations, KV cache, databases, data center class workloads. |
| Use cases | Die-to-die, chip-to-chip, and DRAM bandwidth improvement. |
| Max clock frequency | Up to 2 GHz (Samsung 4nm). |
| Bandwidth at 2 GHz | 512-bit interface: 128 GB/s per direction (compress + decompress). 256-bit interface: 64 GB/s per direction. |
| Compression ratio | Up to 1.5x on LLM weights; an average of 2x on activations and KV cache. |
| Bandwidth improvement | 20–35% across data types, up to 50%. |
| Data interface | AXIStream, 256-bit or 512-bit. |
| Latency | Deterministic and data-independent. Approximately 20 cycles at 2 GHz. |
| Metadata | Approximately 0.05% overhead to track the compression state of each superblock. Managed by the integrator or by the IP. No metadata management needed for C2C / D2D links. |
