Overview

The SuperRAM implements a hardware accelerator for zram compression and decompression. SuperRAM implements a ZeroPoint proprietary compression algorithm and is optimized for power efficiency, high throughput and high compression efficiency.

SuperRAM is integrated on the SoC as other hardware accelerators, as a master node on the SoC interconnect. Part of the integration includes a software driver so that the zram crypto-compress API sends a command to the SuperRAM accelerator when there is a software-triggered compression and decompression.

Key features

  • Compression ratio: 2-4x across diverse data sets
  • Compression throughput: 8GB/s
  • Decompression throughput: 10.5GB/s
  • Frequency: DDR4/DDR5 DRAM speed
  • IP area: Starting at 0.1mm2 (@5nm TSMC)
  • Memory technologies supported: (LP)DDR4, (LP)DDR5, HBM
  • SuperRAM IP is compatible with all DRAM technologies and supports standard interfaces such as AXI and CHI. Other proprietary interfaces can be supported upon request.

Benefits

  • High performance and low latency hardware accelerated zram/zswap at unmatched power efficiency
  • Off-loading CPU – More cycles to released to user work loads
  • Power efficiency – Less energy
  • Speed – Fast compression and low latency access
  • Several in-flight compression and decompression operation operating in parallel
  • Operating at main memory speed and throughput
  • Compatible to AXI4/CHI, both 128-b and 256-b bus interface
  • Intelligent real-time analysis and tuning of the IP Block

Applications

  • Smart device SoCs and Server CPUs.
  • Smart device SoCs: The product benefit is a better user experience at unmatched power efficiency when the host processor is offloaded and the page swapping is hardware accelerated.
  • Server CPUs: The product benefit is more system performance at less power when SW-based compression is off-loaded from the the host. Operating system and hypervisor offload SW-based compression of swapped pages with a super-fast page compression technology and return more performance to the guest at unmatched power efficiency.

Provider

ZeroPoint Technologies AB
HQ: Sweden
ZeroPoint Technologies is a fabless silicon IP (intellectual property) provider of real-time main memory compression and encryption technology. ZeroPoint Technologies is offering a patented memory compression technology for high performance System on a Chip (SoC) processor subsystems. The technology effectively doubles the main memory capacity and memory bandwidth. Our IP-block is placed on the main memory access path and is transparent to the operating system and applications. ZeroPoint also offers main memory encryption, a technology that delivers high throughput and high security memory encryption, integrated with compression or stand alone. ZeroPoint Technologies AB was incorporated in 2015 as a spinout from Chalmers University of Technology. The Intellectual Property Portfolio related to computer memory management was then acquired from the founders and transferred into the new startup. The technology and ideas behind ZeroPoint come from Professor Per Stenström’s research group, which is internationally recognized for research excellence within high-performance computing. Since its creation, ZeroPoint has attracted skilled people from academia, industry, finance and the startup community and raised its first round of Venture Capital in 2016. The headquarter is in Göteborg, Sweden.

Evaluating Lossless Data Compression Algorithms and Cores

Data compression plays a critical role in modern computing, enabling efficient storage and faster transmission of information. Among lossless data compression algorithms, GZIP, ZSTD, LZ4, and Snappy have emerged as prominent contenders, each offering unique trade-offs in terms of compression ratio, speed, and resource utilization. This white paper evaluates these algorithms and their corresponding hardware cores, providing an in-depth comparison to help developers and system architects choose the optimal solution for their specific use case.

Firmware Compression for Lower Energy and Faster Boot in IoT Devices

The phrase “IoT” for Internet of Things has exploded to cover a wide range of different applications and diverse devices with very different requirements. Most observers, however, would agree that low energy consumption is a key element for IoT, as many of these devices must run on batteries or harvest energy from the environment.
