Next, you begin to add hardware components to the SOPC Builder
system. As you add each component, you configure it appropriately to
match the design specifications.
Add the On-Chip Memory
Processor systems require at least one memory for data and instructions.
This example design uses one 20 Kbyte on-chip memory for both data
and instructions. To add the memory, perform the following steps:
1. In the list of available components (on the left-hand side of the
System Contents tab), expand Memories and Memory Controllers,
expand On-Chip, and then click On-Chip Memory (RAM or
ROM).
2. Click Add. The On-Chip Memory (RAM or ROM) MegaWizard
interface appears.
3. In the Block Type list, select M4K.
4. In the Total memory size box, type 20 and select Kbytes to specify a
memory size of 20 Kbytes (see Figure 1–5).
5. Do not change any of the other default settings.
