Human Folly about “Dhrystone”

index

• Cortex M3 (developer.arm.com):

  The #ARM Cortex-M3 (used in many processors of the #STM32 line) has #performance of 1.25 #Dhrystone MIPS/MHz

• SiFive 7 series RISC V cores e76 s76 U74 (cnx-software.com):

  the #RISC-V #SiFive U74 core in the #StarFive JH7110 is about 2.5 #Dhrystone MIPS per MHz, while Roy Longbottom says the Cortex-A53 in the Raspberry Pi 3 is about 2.95 Dhrystone MIPS per MHz #performance

• Raspberry%20Pi%20Benchmarks (roylongbottom.org.uk):

  #Dhrystone #performance results on #Raspberry-Pi: 2201 VAX MIPS for a Pi 3

• Dhrystone%20Results (roylongbottom.org.uk):

  #Dhrystone #performance results for lots of recent systems including Core i7, Android, and Raspberry Pi

• Dhrystone (netlib.org):

  #Performance database server: #Dhrystone benchmarks of many historical machines; a 5x86-133 had 44 DMIPS

• Mecrisp quintus Forth with PicoRV32 on UPduino and 8 queens benchmark (eevblog.com):

  apparently the #PicoRV32 implementation of #RISC-V runs at 12MHz or 24MHz on an ice40UP5k #iCE40 #FPGA but gets half a #Dhrystone MIPS per MHz

• HiFive Unmatched SBC showcases new FU740 RISC V SoC (linuxgizmos.com):

  SiFive’s US$665 HiFive Unmatched board uses a 5-core 1.4 GHz #RISC-V #hardware "FU740" or “Freedom U740” comparable to the #Raspberry-Pi 4’s quad-Cortex-A72. #performance of 2.5 DMIPS/MHz and 4.9 CoreMark/MHz (from which we can deduce that a CoreMark is about 2 #Dhrystone MIPS), dunno if this is per-core or per-chip.
