Maximum Frequencies

In compression mode, the core is tested for all configurations at 170 MHz (s_aclk_250) and 340 MHz (s_aclk_500), whereas 250 MHz for clk_hf uses the Alveo™ U200 accelerator card, which is a -2L speed grade device.

In decompression mode, the core is tested for all configurations at 250 MHz using Alveo™ U200 accelerator card, which is a -2L speed grade device.

Throughput

  • For the compression function, the core has a throughput of 2.67 bytes per clock cycle (s_aclk_250). It varies depending on the input file. For detailed information regarding throughput and CR, please refer to the following graphs.
  • For the decompression function, the core does not have a constant output throughput. It varies depending on the compressed file. For detailed information regarding throughput, refer to the following graphs.
    Note: The throughput and CR data shown above is taken from simulations.
  • For more information on the decompression and compression mode resource utilization, refer to Resource Utilization web page.
