A new article, by Steven Leibson in EE Journal: “Machine Learning: Esperanto coaxes 1092 RISC-V Processors to Dance on the Head of a Pin, er Chip”

Leibson writes:

  • Dave Ditzel has a legendary history with computing and microprocessors. He joined AT&T Bell Labs to work on C language development. While there, he developed several generations of processors designed to execute optimized compiled C programs including CRISP, Bell Labs’s “C-language Reduced Instruction Set Processor.”
  • Ditzel presented details of Esperanto’s ET-SoC-1 ML (machine learning) inference chip at Hot Chips 33 in August. This chip fully displays Ditzel’s long, long association with RISC processors. The ET-SoC-1 ML inference engine incorporates 1092 (that’s “one thousand ninety-two”) customized, 64-bit RISC-V microprocessor cores, 160 Mbytes of on-chip SRAM, and assorted I/O ports – all on one 7nm die.
  • “Ambitious” is an understated word for this chip design.
