32-bit RISC IP extends use of 8051 peripherals/software

June 08, 2015 // By Graham Prophet
Dolphin Integration’s RISC-351 Zephyr microcontroller IP (intellectual property) enables 80x51 users to benefit from 32-bit microcontroller performances while building on the i51 legacy of peripherals and software.

The IP addresses applications which require high processing power with low power consumption. Dolphin Integration says it offers a smooth evolution from i51 to RISC-351, whereas, the company contends, a number of other offerings claim an easy migration, but toward incompatible architectures.

These issues are addressed by providing an optional reduction of the instruction set enabling 1 DMIPS/MHz. At the time when low power consumption is critical the yardstick of 1 DMIPS/MHz enables such an increase of performance that the frequency can be significantly reduced.

RISC-351 preserves 75% of the instructions from the 80x51 family

The same peripheral access bus (SFR) with the same memory mappings enable the reuse of 8051 and 80251 peripherals at no cost

A guided import is provided, of existing 8051 application programs into the new Integrated Development Environment SmartVision including its compiler SmartCC

RISC-351 Zephyr also, Dolphin says, reduces time-to-market by increasing the debugging swiftness for application software thanks to its IDE SmartVision enabling custom peripheral modelling. The new built-in real time debugger enables a comprehensive virtual prototyping and advanced emulation features.

An evaluation kit is available.
