ZeroStorage

A high-performance hardware accelerator for LZ4-compatible compression and decompression, built for clean integration into ASIC and FPGA designs targeting storage and SSD controllers.

What it does

ZeroStorage accelerates standards-based LZ4 compression and decompression in hardware. It is fully software compatible and transparent to the host file system, so it drops into existing storage stacks without changing data formats.

At a glance

LZ4-compatible, fully software compatible
Asymmetric compressor / decompressor
ASIC and FPGA targets (Intel, AMD)
AMBA AXI4-Stream interface
Transparent to the host file system

Where it fits

Storage and media: accelerate compression and decompression for storage and SSD controllers.
DRAM memory: improve bandwidth utilization and capacity through real-time compression.
Streaming data: efficient compression for high-throughput streaming workloads.

Asymmetric by design

The compressor and decompressor can be configured and instantiated completely independently, so you only spend area on the direction and performance you actually need.

Why customers select it

Maximum flexibility through extensive configuration options.
Industry-leading performance per mm² for LZ4 acceleration.
Efficient silicon footprint for advanced ASIC processes and leading Intel and AMD FPGA platforms.

We chose ZeroPoint because we have confidence in their expertise and support, and they are delivering according to schedule at the quality that meets our standards.
