B2B - From Brain to Bits. Today the designers spend 80% of their time on tools and only 20% on the development of the algorithms. hArtes aims to facilitating the realization of designs by making available advanced tools designed with a holistic approach by leading Academies with the cooperation of OEMs.

Minimum TRIMM time. The availability of the hArtes tools will minimize the time spent due to Tools-complexity, Real-time-constraints lost in the design chain, Interface-incompatibility due also to Multi-Methodologies.

Obiettivo: B2B with Minimum TRIMM Time.

•hArtes strategic objective:

–Reduce the application development time by a factor 4

•hArtes approach:

–Start from top level application description and go to the implementation in a “push button” i.e. go from “Brain to Bits” (B2B approach) using an holistic approach to the application and an effective tool chain targeting the embedded domain

Collaboration with students

ATMEL ROMA is extremely interested to collaboration with

universities.

Student imagination and skills lead to brilliant application ideas.
