Operation
3.2.1 Top-Level Symbol and Functional Overview
The DFLPT connects to the AHB as shown in
pipelining (single wait-state), the bus interfaces have little or no combinatorial logic. The
read and address paths connect directly to the registers. The write-path connects to the
register bank through one level 1-hot muxing. All address and locator decodes are also
performed using 1-hot logic. Offset address generated from the AHB address (for purposes
of generating spanned base addresses) use a registered version of the AHB address.
3.2.2 Memory Map
The virtual memory view of the DFLPT can be seen in the figure below. This example
shows how a MPTE can be spanned and how it will appear to the ARM MMU. In this
example, MPTE0 is set as follows:
120
• HW_DIGCTL_MPTE0_DIS = 0x0
• HW_DIGCTL_MPTE0_SPAN = 0x2
