What is CoreMark? CoreMark is a lightweight benchmark suite launched by EEMBC (Embedded Microprocessor Benchmark Consortium) specifically designed to measure the computational power, instruction scheduling, and memory access efficiency of CPU cores. It runs only four core algorithms—linked list, matrix multiplication, state machine, and CRC check—making it both compact (the source code is less than … Read more
Introduction Brothers, what is the most concerning thing when writing code and debugging chips? That’s right, it’s not knowing how fast your processor really is. Running a few demos and checking a few lines of logs is simply unreliable. Thus, the industry has introduced CoreMark—a lightweight benchmark specifically designed to measure CPU core performance. Today, … Read more
What is CoreMark? CoreMark is essentially a “tool” designed specifically for benchmarking embedded CPUs. Its goal is straightforward: to measure the computational power of the processor core without considering peripherals or operating systems, which are often seen as unnecessary distractions. Imagine you have a newly purchased MCU and want to know how fast it runs … Read more
Don’t Just Benchmark Phones! A Comprehensive Guide to Linux Performance Testing When people mention “benchmarking”, the first thing that comes to mind is usually mobile phone tests like AnTuTu or computer tests like 3DMark—either on Windows or Android. But did you know that you can also benchmark on Linux? It’s not just about getting a … Read more
The “Performance Evaluation Action for Typical Server Application Scenarios” has officially launched!—— In order to standardize the construction of a full-stack standard system, promote product technology iteration and upgrade, better showcase the advantages of the entire architecture and computing power, and support excellent products and solutions to enhance their brand and market expansion through official … Read more
RTOS Benchmark is a test suite specifically designed to measure the core operation performance of Real-Time Operating Systems (RTOS). It quantifies the time and overhead of basic operations such as thread creation/switching, mutex/semaphore, timers, and message queues through a series of benchmark tests. Currently, it mainly supports Zephyr (qemu_x86, frdm_k64f) and FreeRTOS (frdm_k64f), with plans … Read more
