Gpmc ((exclusive))

Modern SoCs (Systems on Chip) are packed with dedicated SPI, I2C, and UART peripherals. However, those interfaces are serial—they are slow. When you need high throughput or deterministic low latency, parallel buses reign supreme.

At its core, the GPMC is a hardware memory controller that acts as a bridge between the processor’s internal memory bus and external memory-mapped devices. To the CPU, reading from an external FPGA or writing to an LCD controller looks exactly like reading from a local RAM address—thanks to the GPMC. Modern SoCs (Systems on Chip) are packed with
