This document is one of the five standards of the automotive chip certification review series: RB/T 133 (general evaluation requirements), RB/T 134 (design organizations), RB/T 222 (certification bodies), RB/T 247 (testing organizations) and RB/T 248 (computing chip testing).

This document was drafted in accordance with the rules given in GB/T 1.1-2020.

This document was proposed by and is under the jurisdiction of CNCA. Drafting organizations: Certification and Accreditation Technology Research Center of SAMR; Certification Supervision Department of SAMR.

Introduction

With the rapid development of intelligent and connected vehicles, chip computing power has become a key indicator of vehicle performance. The industry generally relies on TOPS (tera operations per second) as a single indicator, which does not reflect the effective computing capability of a chip in complex scenarios and makes chip selection and industrial application difficult.

To build a scientific evaluation system, this document proposes a multi-dimensional evaluation method of basic computing power plus effective computing power, and standardizes the test requirements and the capability of the organizations that carry out the evaluation, so that the results are true, reliable and traceable.

1 Scope

This document specifies the technical requirements, indicator system and evaluation method for evaluating the computing power of automotive chips.

This document is applicable to the capability admission conditions and certification review requirements of computing power evaluation and testing organizations and of computing chip design organizations.
