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.
