WebThe RDCYCLE pseudoinstruction reads the low XLEN bits of the cycle CSR which holds a count of the number of clock cycles executed by the processor core on which the hart is running from an arbitrary start time in the past. RDCYCLEH is an RV32I-only instruction that reads bits 63–32 of the same cycle counter. Webrdtsc counts reference cycles, not CPU core clock cycles It counts at a fixed frequency regardless of turbo / power-saving, so if you want uops-per-clock analysis, use performance counters. rdtsc is exactly correlated with wall-clock time (not counting system clock adjustments, so it's a perfect time source for steady_clock ). burlington pediatrics fax number

WebOct 7, 2024 · The 32-bit hardware clock is a high precision counter that tracks time in unspecified units called cycles. The duration of a cycle is determined by the board hardware used by the kernel, and is typically measured in nanoseconds. The 64-bit system clock is a counter that tracks the number of ticks that have elapsed since the kernel was initialized.
