15. About JTAG Daisy Chain and SWD
In the JTAG interface, the most commonly used signals are four: TCK/TMS/TDO/TDI. The JTAG interface can be used one-to-one, or can form a daisy chain one-to-many topology. The two topologies are shown in the figure below. In multi-core chips, the internal chips have already been connected in a daisy chain form.
Additionally, for SWD, please refer to the classic article below:

16. Analysis of ARM Cortex-X4 Microarchitecture
The code name of Cortex-X4 is Hunter-ELP, the figure below is the microarchitecture diagram of X4. The first impression is that it has become “larger”. The core of X4 has become larger and larger, and everyone should feel that this microarchitecture design is increasingly resembling another industry-leading processor. Different paths lead to the same destination; the best designs often have only one choice. We will analyze this year’s core changes in detail below.
