Memory Mapped I/O

Memory mapped I/O is a technique that maps device hardware registers or buffers into the memory address space of an application. This allows the application to read from or write to the hardware as if it were accessing standard system memory.

In high-frequency trading, this is used to interact with network interface cards or FPGAs without the need for slow system calls. By accessing hardware directly, the trading application achieves much faster data transfer and control.

It is a fundamental technique for building low-latency trading systems. This method requires careful management of memory access and synchronization to avoid conflicts.

It is a powerful tool that brings the speed of hardware directly to the software application. Memory mapped I/O is a key component of modern high-performance driver development.

It is essential for achieving the lowest possible latency in data-intensive trading applications.
