Preliminary
On-chip Data Memories
DMU Scratch-Pad SRAM (DSRAM):
The DMU memory consists of 24-KByte Data Scratchpad RAM (DSRAM) and 8-KByte
Data Cache (DCACHE).
Address range of the DSRAM:
• D000 0000_H - D000 5FFF_H
Local Memory Bus Memory (LMBRAM):
Address range of the 64 KByte Local Memory Bus Memory:
• C000 0000_H - C000 FFFF_H (in segment 12 for cached operation)
• E800 0000_H - E800 FFFF_H (in segment 14 for non-cached operation)
FPI-Bus Data Memory (FPIDRAM):
The FPI-Bus Data Memory (FPIDRAM) is a 16-KByte static RAM located on the FPI-
Bus. It contains two parts: FPIDRAM0 and FPIDRAM1. One half of it (FPIDRAM1) can
be used for standby power operation.
Address range of the FPI Data Memory:
• 9FFF 8000_H - 9FFF BFFF_H (in segment 9 for cached operation)
• BFFF 8000_H - BFFF BFFF_H (in segment 11 for non-cached operation)
On-chip PCP Memories
PCP Code Memory (PCODE):
The address range of the 16 KByte PCP Code Memory (PCODE) is:
• F002 0000_H - F002 3FFF_H
PCP Data Memory (PRAM):
The address range of the 4 KByte PCP Data Memory (PRAM) is:
• F001 0000_H - F001 0FFF_H
