DP80390 Datasheet Pipelined High Performance 8-bit Microcontroller

Manufacturer: Digital Core Design

Overview: .. DP80390 Pipelined High Performance 8-bit Microcontroller ver 4.02 OVERVIEW DP80390 is an ultra high performance, speed optimized soft core of a single-chip 8bit embedded controller dedicated for operation with fast (typically on-chip) and slow (offchip) memories. It supports up to 8 MB of linear code and 16 MB of linear data spaces. 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. DP80390 soft core is 100% binarypatible with the industry standard 80390 & 8051 8-bit microcontrollers. There are two configurations of DP80390: Harward where internal data and program buses are separated, and von Neumann with mon program and external data bus. DP80390 has Pipelined RISC architecture 10 times faster pared 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. DP80390 is delivered with fully automated testbench and plete set of tests allowing easy package validation at each stage of SoC design flow.
