12.5. Vector Narrowing Fixed-Point Clip Instructions vnclip指令用于将一个定点数归约到一个目的向量中. 该指令支持rounding, scaling和饱和. vs2指定了源数据, vs1指定了scale的shift amount 具体的round模式由vxrm CSR寄存器指定. round在目的寄存器的低位进行, 先于饱和操作 如果目的元素存在饱和的情况, 则vxsat...

7. Write mstatus.FS to enable floating-point (if supported). 8. Store machine mode user registers to stack or to an application specific frame pointer. 9. Write mepc with the entry point of user mode software 10. Execute mret instruction to enter user Mode. 1. 首先通过将 mstatus.MIE ...
from my point of view, as long the conditions are the same, yes. Are that results true enough? from my point of view, maybe. At least two cases does not match: the DarkRISCV reaches up to 240MHz in the same FPGA when the top level is in the build. Not sure why the core only...
Notable features of the RISC-V ISA include a load–store architecture, bit patterns to simplify the multiplexers in a CPU, IEEE 754 floating-point, a design that is architecturally neutral, and placing most-significant bits at a fixed location to speed sign extension. The instruction set is de...
(Linux) on macOS, you will need to build within a case-sensitive file system. The simplest approach is to create and mount a new disk image with a case sensitive format. Make sure that the mount point does not contain spaces. This is not necessary to build newlib or gcc itself on ...

There are very few fixed things. Nearly everything is plugin based. The PC manager is a plugin, the register file is a plugin, the hazard controller is a plugin, ... There is an automatic a tool which allows plugins to insert data in the pipeline at a given stage, and allows other ...
3.8. Vector Fixed-Point Rounding Mode Register vxrm 矢量定点舍入模式寄存器的最小有效位(vxrm[1:0])是一个两位读写的舍入模式字段。高位(vxrm[XLEN-1:2])应写为零。 矢量定点舍入模式有一个单独的 CSR 地址,允许独立访问,但也反映为 vcsr 中的一个字段。
