Latest White Paper
IoT devices that employ code shadowing can enjoy significant energy savings by using efficient hardware code compression. The compressed application code needs a smaller NVM device for long-term storage, and the system consumes significantly less time and energy reading the compressed code from the system's non-volatile memory (NVM) into the on-chip SRAM. The code can be decompressed in-line (as it is read out of the NVM), at the cost of practically negligible additional delay or energy usage.

Background & More Info
GZIP-RD-KU105 ZipAccel-C GZIP PCIe Reference Design
The GZIP-RD-KU105 is a reference design for a PCIe data compression acceleration card using the ZipAccel-C GZIP/ZLIB/Deflate Compression IP Core.
The design runs on the Xilinx® Kintex® UltraScale™ FPGA KCU105 Evaluation Kit and it is built on top of Xilinx’s KCU105 PCI Express Streaming Data Plane targeted reference design (TRD). The package includes Linux Kernel drivers and a sample GUI-driven application.
The reference design achieves lossless data compression rates exceeding 23 Gbps. The reference design is suitable for servers or databases where it optimizes storage requirements or network bandwidth. Designers can use the sample application to evaluate the performance of the ZipAccel-C core, or can develop their own application using the API to the drivers.
The compression core itself can provide throughputs exceeding 60 Gbps. Modifications to the reference design to achieve higher rates or to port the design to other boards or FPGA devices are available.
Included GUI for control and monitoring of the reference design.
