Memory interface
EmbeddedICE Logic
The ARM7TDMI processor memory interface has been designed to allow performance
potential to be realized, while minimizing the use of memory. Speed-critical control
signals are pipelined to allow system control functions to be implemented in standard
low-power logic. These control signals facilitate the exploitation of the fast-burst access
modes supported by many on-chip and off-chip memory technologies.
The ARM7TDMI core has four basic types of memory cycle:

EmbeddedICE Logic is the additional hardware provided by debuggable ARM
processors to aid debugging. It allows software tools to debug code running on a target
processor. The EmbeddedICE Logic is controlled through the Joint Test Action Group
(JTAG) test access port, using the EmbeddedICE interface. See Chapter 5 Debug
Interface and Appendix B Debug in Depth for more information.
