Coresight has two main functions: debugging and tracing. 1. Debugging The debugger implements debugging functionality through DAP. 1.1. Single-Core Debugging System: One DAP, along with one AP and APBIC. External access to the DP is transformed by the DAP into AP access. The AP generates the AP bus through the APBIC, allowing access to debugging … Read more
Years ago, a system-on-chip (SoC) with one million transistors was considered a large device, but today, SoCs with up to one billion transistors are common. Driven by Moore’s Law and the continuous reduction in process sizes, to further meet the performance requirements of applications, the integration of SoC chips has become increasingly high, and system … Read more
Source: Chip Theory Introduction: Today’s CPUs or SoCs are basically integrated with multiple CPU cores on a single chip, forming what is commonly referred to as 4-core, 8-core, or more core CPUs or SoC chips. Why adopt this method? How do multiple CPU cores work together? Is more CPU cores always better? With these questions … Read more
1. Reasons for CPU Usage Over 100% in top CommandIn Linux systems, a process’s CPU usage exceeding 100% in the top command can have multiple reasons.(1) Factors Related to Multi-Core Processors 1. Characteristics of Multi-Core CPUs – For multi-core processor systems, the top command divides CPU usage by the number of cores and displays it … Read more
