DP80390CPU Pipelined High Performance 8-bit Microcontroller ver 3.10 OVERVIEW DP80390CPU 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. DP80390CPU soft core is 100% binarycompatible with the industry standard 80390 & 8051 8-bit microcontroller. There are two configurations of DP80390CPU: Harward where internal data and program buses are separated, and von Neumann with common program and external data bus. DP80390CPU 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. DP80390CPU is delivered with fully automated testbench and complete set of tests allowing easy package validation at each stage of SoC design flow. ● ○ ○ CPU FEATURES 100% software compatible with industry standard 80390 & 8051 LARGE mode – 8051 instruction set FLAT mode – 80390 instruction set ● Pipelined RISC architecture enables to execute instructions 10 times faster compared to standard 8051 24 times faster multiplication 12 times fast……
