The Kernel Cornerstone of Linux Concurrency Programming: In-Depth Analysis of fork(), clone(), and pthread

When building high-performance, highly concurrent Linux applications, understanding the underlying mechanisms of processes and threads is crucial. <span>fork()</span> and <span>clone()</span> are two core system calls that not only form the basis of process creation but also directly impact the implementation and performance of threads. This article will delve into the workings of <span>fork()</span> and <span>clone()</span> … Read more

FPGA Configuration Modes

FPGA Configuration Modes

FPGA has various configuration modes: the parallel master mode involves one FPGA and one EPROM; the master-slave mode supports programming multiple FPGAs with one PROM; the serial mode can use serial PROM to program the FPGA; and the peripheral mode allows the FPGA to be programmed by a microprocessor as a peripheral device. How to … Read more

Troubleshooting a Nearly Scrapped Board: Finding the Cause After a Week

Documenting an Issue Related to ALTERA Device JTAG While reviewing previous blog posts, I found several published years ago related to JTAG, specifically: the first one discusses connecting multiple devices on a single JTAG chain: https://mbb.eet-china.com/blog/1010859-213144.html. The second one involves an interesting issue encountered during automatic detection (AUTO Detect) via JTAG interface with the download … Read more
