This release provides a new DE5-Net worker image. The new worker image provides:

  • 64 cores
  • 16 threads per core
  • (1024 threads in total)
  • 16 mailboxes
  • 16 caches
  • 16 floating-point units
  • 2D network-on-chip (new)
  • two DDR3 DRAM controllers
  • four QDRII++ SRAM controllers (new)
  • four 10Gbps reliable links
  • a JTAG UART

The clock frequency is 250MHz and the resource utilisation is 135K ALMs, 58% of the DE5-Net. Notably, the DE5-Net's off-chip SRAMs are now memory mapped into the Tinsel address space.

The POLite frontend has also been extended to use the off-chip SRAMs and to support more efficient multi-casting, although there's still no support for R-devices yet.

This release also includes tweaks that make the power-reset mechanism more robust.
