Pipelined High Performance
8-bit Microcontroller
ver 3.10
OVERVIEW
DP80390XP is an ultra high perform-
ance, speed optimized soft core of a single-
chip 8-bit embedded controller dedicated for
operation with fast (typically on-chip) and slow
(off-chip) memories. The core has been de-
signed with a special concern about perform-
ance to power consumption ratio. This ratio
is extended by an advanced power manage-
ment unit PMU.
DP80390XP soft core is 100% binary-
compatible with the industry standard 80390 &
8051 8-bit microcontroller. There are two con-
figurations of DP80390XP: Harward where
internal data and program buses are sepa-
rated, and von Neumann with common pro-
gram and external data bus. DP80390XP has
Pipelined RISC architecture 10 times faster
compared to standard architecture and exe-
cutes 85-200 million instructions per second.
This performance can also be exploited to
great advantage in low power applications
where the core can be clocked over ten times
more slowly than the original implementation
for no performance penalty.
DP80390XP is fully customizable, which
means it is delivered in the exact configuration
to meet users’ requirements. There is no need
to pay extra for not used features and wasted
silicon. It includes fully automated testbench
with complete set of tests allowing easy
package validation at each stage of SoC de-
sign flow.
