DP8051CPU
Pipelined High Performance
8-bit Microcontroller
ver 4.02
OVERVIEW
DP8051CPU 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.
DP8051CPU soft core is 100% binary-
compatible with the industry standard 8051 8-
bit microcontroller. There are two configura-
tions of DP8051CPU:
Harward
where internal
data and program buses are separated, and
von Neumann
with common program and ex-
ternal data bus. DP8051CPU has Pipelined
RISC architecture
10 times faster
compared
to standard architecture and executes
85-200
million instructions
per second. This per-
formance can also be exploited to great advan-
tage in
low power
applications where the core
can be clocked over ten times more slowly
than the original implementation for no per-
formance penalty.
DP8051CPU is delivered with
fully auto-
mated testbench
and
complete set of tests
allowing easy package validation at each stage
of SoC design flow.
