Makefile的内容就介绍到这里,下面以tinyriscv项目里的tests/example/simple例程来具体分析。 tests/example/simple/Makefile文件内容如下: RISCV_ARCH:= rv32imRISCV_ABI:= ilp32RISCV_MCMODEL:= medlowTARGET=simpleCFLAGS+= -DSIMULATION#CFLAGS += -O2#ASM_SRCS +=#LDFLAGS +=#INCLUDES += -I.C_SRCS:...
$ git clone https://github.com/riscv/riscv-tests $ cd riscv-tests $ git submodule update --init --recursive $ autoconf $ ./configure --prefix=$RISCV/target $ make $ make install The rest of this document describes the format of test programs for the RISC-V architecture....
事实上,tinyriscv就是这么做的。 RISC-V的中断(异常)架构与ARM相比,其中有一点是做得非常好的,那就是RISC-V的中断(异常)入口地址是可以通过软件修改的(修改mtvec寄存器的值),而不像ARM那样硬件设计好了就不能变了。这样的好处是,在移植freertos时就可以共用原有(其他例程)的启动代码,只需要在系统初始化时设...
After lots of tests with different cores, I found thepicorv32core and the all the ecosystem around the RISC-V. Thepicorv32is a very nice project and can peak up to 150MHz in a low-cost Spartan-6. Although most instructions requires 3 or 4 clocks per instruction, thepicorv32resembles ...
