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. 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. DP80390CPU soft core is 100% binarypatible 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 mon program and external data bus. DP80390CPU has Pipelined RISC architecture 10 times faster pared to standard architecture and executes 85-200 million instructions per second. This...
