DP8051XP
Pipelined High Performance
8-bit Microcontroller
ver 3.10
OVERVIEW
DP8051XP is a 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 about performance to
power consumption ratio. This ratio is ex-
tended by an advanced power management
unit PMU.
DP8051XP soft core is 100% binary-
compatible with the industry standard 8051 8-
bit microcontroller. There are two configura-
tions of DP8051XP: Harward where internal
data and program buses are separated, and
von Neumann with common program and ex-
ternal data bus. DP8051XP 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.
DP8051XP 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.
