Role of IFC
−
After the power is turned on, a typical system:
1.
Starts execution from non-volatile memory, typically NOR/NAND
flash memory
2.
Copies the code to main memory (DDRx)
3.
Starts the execution from the main memory

A system must be able to talk to non-volatile memory
without any software configuration steps
• IFC is the controller that does this initial booting job
− IFC
has three controllers:
NOR controller

−
Standard and page mode NOR flash
−

External latch is not needed for the address bus.
Address is latched internally inside NOR flash.
•
IFC_ADDR[24] must be left out for the 16-bit port.
•
After power on reset, CSORn[PGRD_EN] is set to 0.
Software must set this bit to enable page read mode.
•
When choosing the page-mode flash, the page size must be the
same as the cache line, i.e., 32 bytes.
•
In order to take advantage of the page mode
- Use DMA to copy the code from NOR flash to DDR
- Enable cache

•
Higher-density / lower-cost than regular flash (NOR flash)
IO device using commands to read/write
No address bus
• Page-oriented, not suitable for random access
•
•
Possible bit error
Usually a certain number of blocks are marked bad by the
manufacturer
• During the operation, more blocks can go bad
• ECC is a must
•
•
No execute in place (XIP)
•

•
Long wait time for random address
Possible bit error only known after the whole page read and ECC

Option for external termination by IFCTA
CSORn[RGETA], CSORn[WGETA]
0: Terminated by the internal TRAD counter for the read or TWP for the
write
or IFCTA if it is asserted earlier than the internal timer expiration
1: Only terminated by the assertion of IFCTA, not the internal timer.
•
This feature is useful if the response time is variable.
