Abstract

A high-performance RISC-VLIW reconfigurable Digital Multi-processor invention has been smoothly crossing generations, arriving as an advanced Processor Platform. The results of the works feature a fusion of several advanced processor technologies:
  1. Application: low-power-consumption parallel processing covering conventional application fields of DSP(Digital Signal Processor), DMP(Digital Media Processor) and SPP(Super Parallel Processors);
  2. Architecture: RISC and VLIW mixed within the same configuration platform;
  3. Computing Power: Processor Arrays are configurable with heterogeneous instances of common cores (formed by commonly used ALU, etc.) and dedicated cores (formed by designer designed computing units);
  4. Configurability: Silicon Compiler, SoC Composer, Designer Defined Computing Units, Inter-core and Intra-slot Pipeline, Field Upgradable including DDCU;
  5. Dedicated design automations with commercial-grade tools for design, analysis and verification, interfaced with popular EDA flows;
  6. Product Models: Silicon IP, General-purpose Processor ICs and Custom SoC products. Namingly "FusionDMP"(Digital Multi-processor Platform), it brings together a number of different processor technologies into a single, unified architecture and environment. This new breed of processor will fuel growth and development for the next generation of IC designs.
This article is Beijing XHMicro’s Fusion Team’s first time introducing Fusion Processor Platform to public. It demonstrates the Platform’s concept formation; walks through the team’s clues of trade-offs in parallel processing. Then it described key elements of the processor, such as RISC-VLIW mixed architecture, heterogeneous multi-cores, pipelines, designer defined computing units, compiler, etc. along with example algorithms, referenced by an early-stage results. Furthermore addressed are: interactive and automated means of processor’s architecture compiler, SoC composer and verifications. The entire Fusion Processor Platform technology is a sophisticated system-engineering project.

摘要

一种高性能、RISC-VLIW融合的多核、可重构数字媒体处理器已经从专利发明顺利形成了一个先进的数据处理器设计平台（Digital Multi-processor Platform）。研发的结果体现若干先进处理器技术的融合。
  1. 应用：低功耗并行运算处理覆盖数字信号处理(DSP)、数字媒体处理(DMP)和超级并行处理器(SPP)的应用扩展领域；
  2. 体系结构：精简指令(RISC)和超常指令字(VLIW)处理器融合于同一个可配置的平台；
  3. 运算能力：处理器群调用异构的通用处理器核，使用两类处理器核实例：通用处理器核（包括ALU等的通用运算）和专用处理器核（包括DDCU的用户自定义运算核）；
  4. 可配置和可重构：硅编译器、SoC集成工具、用户自定义运算单元、多核间的和槽内的流水线、包括运算单元的现场编程；
  5. 设计自动化平台：专用工具用于设计、分析与验证；与商业电子自动化设计(EDA)流程接口；
  6. 产品模式：硅知识产权(Silicon IP)、通用处理器芯片系列(IC Series)、定制单片系统(SoC)。命名为Fusion的"融合式数字多核处理器平台"把数个先进处理器技术集成到一个统一的体系结构和设计环境之中，这个平台技术将推动集成电路芯片设计业的跨代增长和发展。
本文是北京芯慧同用微电子技术公司Fusion团队第一次向公众介绍Fusion的融合式多核处理器平台。文章演示了处理器平台概念的形成；介绍了处理体系结构上的取舍。进而，讲解了RISC-VLIW融合的体系结构、多核异构的应用实例、 用户自定义的运算单元、编译器等及其举例说明，并给出初期的基准测试结果。最后介绍了交互和自动化的处理器配置和验证的工具流程。整个融合式处理器平台的研发是一个复杂的系统工程项目。
