LICENSING

Comprehensible and clearly defined licensing

methods without royalty fees make using of IP

Core easy and simply.

Single Design

license allows use IP Core in

single FPGA bitstream and ASIC implementa-

tion.

Unlimited Designs, One Year

licenses allow

use IP Core in unlimited number of FPGA bit-

streams and ASIC implementations.

In all cases number of IP Core instantiations

within a design, and number of manufactured

chips are unlimited. There is no time restriction

except One Year license where time of use is

limited to 12 months.

DESIGN FEATURES

♦

PROGRAM MEMORY:

The DP80390 soft core is dedicated for

operation with Internal and External Pro-

gram Memory. It maximal linear size is

equal to 16 MB. Internal Program Memory

can be implemented as:

○

ROM located in address range between

0000h

÷ (ROM

○

RAM located in address range between

External Program Memory can be im-

plemented as ROM or RAM located in ad-

♦

INTERNAL DATA MEMORY:

The DP80390CPU can address Internal

Data Memory of up to 256 bytes The Inter-

nal Data Memory can be implemented as

Single-Port synchronous RAM.

♦

EXTERNAL DATA MEMORY:

The DP80390CPU soft core can address

up to 16 MB of External Data Memory. Ex-

tra DPX (Data Pointer eXtended) register is

used for segments swapping.

♦

USER

Up to 104 External (user) Special Func-

tion Registers (ESFRs) may be added to

the DP80390CPU design. ESFRs are

memory mapped into Direct Memory be-

tween addresses 80 hex and FF hex in the

same manner as core SFRs and may oc-

cupy any address that is not occupied by a

core SFR.

♦

WAIT STATES SUPPORT:

The DP80390CPU soft core is dedicated

for operation with wide range of Program

and Data memories. Slow Program and Ex-

ternal Data memory may assert a memory

Wait signal to hold up CPU activity.
