• The A64 ISA and Compilers
    Fact: The ARM architecture is the most widely licensed 32-bit embedded instruction set architecture in the industry. That fact makes the ARM Instruction Set Architecture (ISA) incredibly important...
  • A walk through of the Microarchitectural improvements in Cortex-A72
    In early 2015, ARM announced a suite of IP for Premium Mobile designs, with the ARM® Cortex®-A72 Processor delivering a 3.5x increase in sustained delivered performance over 28nm Cortex-A15 designs from...
  • Neoverse N1 CPU Questions
    Hi! I would like more clarification on the Neoverse N1 CPU. How many cores does the CPU have? I saw on the network that the motherboard has FPGA, so with the FPGA you can bring a maximum of 96 cores...
  • Cortex-A9 Branch prediction to speculative execution
    Hi, I am building a cycle accurate simulator for the Cortex-A9 core, and so far I constructed most of the stages of the pipeline. However I am having trouble placing something that is not clear in any...
