Address Translation Process for Overlay into OVRAM
In each enabled overlay block control logic, three registers hold the information to control
the overlay functionality:
•
The overlay target address in the Overlay Target Address Register OTARx, which
determines the base address of the program or OLDA memory data block x to be
redirected.
•
The base address of the overlay memory block in the OVRAM, external memory or
EMEM (if emulation Device) in the Redirected Address Base Register RABRx, and
the related enable and control bits.
•
A mask in the Overlay Mask Register OMASKx, defining the size of the block, the
address bits to be checked for an address match, and which bits are used from the
redirected address base and which from the original data address.
The size of the overlay memory blocks can be 2
n
times the minimal block size (16 byte
for internal memory overlay or 1 Kbyte for Emulation Memory overlay, respectively) with
