10 OVERVIEW CPU FEATURES ● ○ ○ DP80390XP is an ultra high performance, speed optimized soft core of a singlechip 8-bit embedded controller dedicated for operation 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 extended by an advanced power management unit PMU.
DP80390XP soft core is 100% binarycompatible with the industry standard 80390 & 8051 8-bit microcontroller.
There are two configurations of DP80390XP: Harward where internal data and program buses are separated, and von Neumann with common program and external data bus.
DP80390XP has Pipelined RISC architecture 10 times faster compared to standard architecture and executes 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 design flow.
