Epiphany-V: A 1024-core 64-bit RISC processor

Epiphany-V: A 1024-core 64-bit RISC processor

   I am happy to report that we have successfully taped out a 1024-core Epiphany-V RISC processor chip at 16nm.  The chip has 4.5 Billion transistors, which is 36% more transistors than Apple’s latest 4 core A10 processor at roughly the same die size. Compared to leading HPC processors, the chip demonstrates an 80x advantage in processor density and a 3.6x advantage in memory density.
  Epiphany-V Summary:

  
       
  • 1024 64-bit RISC processors   
  • 64-bit memory architecture   
  • 64-bit and 32-bit IEEE floating point support   
  • 64 MB of distributed on-chip SRAM   
  • 1024 programmable I/O signals   
  • Three 136-bit wide 2D mesh NOCs   
  • 2052 separate power domains   
  • Support for up to One Billion shared memory processors   
  • Support for up to One Petabyte of shared memory   
  • Binary compatibility with Epiphany III/IV chips   
  • Custom ISA extensions for deep learning, communication, and cryptography   
  • TSMC 16FF process   
  • 4.56 Billion transistors, 117mm^2 silicon area   
  • DARPA funded  
   Chips will come back from TSMC in 4-5 months. We will not disclose final power and frequency numbers until silicon returns, but based on simulations we can confirm that they should be in line with the 64-core Epiphany-IV chip adjusted for process shrink, core count, and feature changes. For a more complete description of the new Epiphany-V chip read this report.
  Cheers,
  Andreas
