4.8. Retry slave

The retry slave is a rudimentary module that is used to demonstrate how to build an AHB slave. The example contains very little functionality and consists of four 32-bit wide registers. The slave generates various logic functions of these registers, which can be read from different locations.

One of the most important features of the slave is that the response that it gives can be varied according to the high order address lines. Figure 4.30 shows the retry slave block diagram.
