首先,你要好好学习一下[1] RISC-V指令集手册中的“Chapter 10 Extending RISC-V”,这里明确介绍了给RISC-V指令集扩展指令的规则。包括标准的扩展和非标准扩展两个方面。非标准扩展也就是我们f Standard versus Non-Standard ExtensionAny RISC-V processor implementation must support a base integer ISA (RV32I...

RISC-V标准中定义了两个主要变种 32位字长指令 64位字长指令 除上述两种主要指令长度的指令集之外,还对描述了128位的指令集实现基本思想,即将其视为32位和64位指令的扩展,但是并没有给出具体的设计,因为现阶段并没有如此长指令的开发经验。 RISC-V项目2010年由加利福尼亚大学伯克利分校着手开发,但是现阶段有许多...
The 64-bit NX27V is a vector processor with 5-stage scalar pipeline that supports the latest RISC-V specification, including the IMAFD standard instructions, “C” 16-bit compression instructions, “P” DSP extension instructions, “V” vector extension instructions and “N” for user-level in...
Munich, Germany -- June 4, 2024 –Codasip, the leader in RISC-V Custom Compute, has introduced a new low-power embedded processor core, and the next generation of processor design automation toolset Codasip Studio. Codasip L110 delivers best-in-class performance for power-sensitive applications....
This thesis uses Verilog HDL language to design and implement the processor core, and in order to better achieve the verification goal, this thesis designs a simple SoC system with UART transmission function, clock interrupt function, and display function. Then, it builds a RISC-V compilation...
整数通用寄存器组(Integer Register File,简称Integer-Regfile)模块主要用于实现RISC-V架构定义的整数通用寄存器组,其微架构如图4所示。RISC-V的整数指令都是单操作数或两操作数指令,且蜂鸟E203属于单发射(一次发射派遣一条指令)的微架构,因此Integer-Regfile模块只需要支持最多两个读端口。同时,蜂鸟E203的写回策略是...
