DR8051XP is a high performance, area
optimized soft core of a single-chip 8-bit em-
bedded controller dedicated for operation with
fast (typically on-chip) and slow (off-chip)
memories. The core has been designed with a
special concern about low power consump-
tion. Additionally an advanced power man-
agement unit makes DR8051XP core perfect
for portable equipment where low power
consumption is mandatory.

● 100% software compatible with industry
standard 8051
● RISC architecture enables to execute in-
structions 6.7 times faster compared to
standard 8051
● 12 times faster multiplication
● 9.6 times faster division
DR8051XP soft core is 100% binary-
compatible with the industry standard 8051 8-
bit microcontroller. There are two configura-
tions of DR8051XP: Harward where external
data and program buses are separated, and
von Neumann with common program and ex-
ternal data bus. DR8051XP has RISC architec-
ture 6.7 times faster compared to standard
architecture and executes 65-200 million in-
structions per second. This performance can
also be exploited to great advantage in low
power applications where the core can be
clocked up to seven times more slowly than
the original implementation for no performance
penalty.
