Introduction to Timers In ZYNQ embedded systems, timer resources are abundant. Each Cortex-A9 processor has its own independent 32-bit private timer and a 32-bit watchdog timer, while both CPUs share a single 64-bit Global Timer Counter (GTC). System Block Diagram Global Timer (GTC) The Global Timer is a 64-bit incrementing counter with an automatic increment … Read more
01 ARM Cortex-A9 Registers For the ARM Cortex-A9 processor, its registers mainly consist of two parts: general-purpose registers and system control registers. The general-purpose registers shown in the figure above are primarily used during code execution, allowing the CPU to execute code and perform related arithmetic operations. During debugging, the registers of particular interest are … Read more
