ADSP-2192 PCI Memory Map

 

 

Data Word. BAR3 Mode is typically used for Data Memory

 

The ADSP-2192 On-Chip Memory is mapped to the PCI

Access. Only the 16 MSBs of a Data Word are accessed in

 

 

 

 

 

 

Address Space. Because some ADSP-2192 Memory Blocks

24-bit Blocks; the 8 LSBs are ignored.

 

are 24-bits wide (Program Memory) while others are

 

16-bits (Data Memory), two different footprints are avail-

 

able in PCI Address Space. These footprints are available to

 

each PCI function by accessing different PCI Base Address

 

Registers (BAR).

 

BAR2 supports 24-bit “Unpacked” Memory Access. BAR3 supports 16-bit “Packed” Memory Access.

In 24-bit (BAR2) Mode, each 32 bits (4 Consecutive PCI Byte Address Locations, which make up one PCI Data word) correspond to a single ADSP-2192 Memory Loca- tion. BAR2 Mode is typically used for Program Memory Access. Byte3 is always unused. Bytes[2:0] are used for

24-bit Memory Locations. Bytes[2:1] are used for 16-bit Memory Locations as shown in the example figure.
