7.1 Architectural overview
The ARM Cortex-M3 includes three AHB-Lite buses: the system bus, the I-code bus, and
the D-code bus. The I-code and D-code core buses are faster than the system bus and
are used similarly to Tightly Coupled Memory (TCM) interfaces: one bus dedicated for
instruction fetch (I-code) and one bus for data access (D-code). The use of two core
buses allows for simultaneous operations if concurrent operations target different devices.
