DP80C51
Pipelined High Performance
8-bit Microcontroller
ver 4.01
OVERVIEW
DP80C51 is an
ultra high performance,
speed optimized
soft core of a single-chip 8-
bit embedded controller dedicated for opera-
tion with
fast
(typically on-chip) and
slow
(off-
chip)
memories.
The core has been designed
with a special concern for
performance to
power consumption
ratio. This ratio is ex-
tended by an advanced power management
unit
PMU.
DP80C51 soft core is 100% binary and
pin compatible
with the industry standard
8051 8-bit microcontroller. There are two con-
figurations of the DP80C51:
Harward,
where
external data and program buses are sepa-
rated, and
von Neumann,
with common pro-
gram and external data bus. DP80C51 has
Pipelined RISC architecture up to
10 times
faster
compared to standard architecture and
executes
85-200 million instructions
per
second. This performance can also be ex-
ploited to great advantage in
low power
appli-
cations where the core can be clocked over ten
times more slower than the original implemen-
tation for no performance penalty.
DP80C51 is delivered with
fully auto-
mated testbench
and
complete set of tests
allowing easy package validation at each stage
of SoC design flow.
