.insn r opcode, func3, func7, rd, rs1, rs2 注意:其他type的insn写法见参考2 opcode需使用上述RISC-V base opcode map表格custom-0/custom-1/custom-2/custom-3中的一种,func3/func7字段可以自定义,注意不要超过了位宽限制。 硬件实现了这条自定义指令后,接下来就是软件上使用了。 汇编语句: .ins...
8_t myConstVariable_3 __attribute__((section(".test_address_1"))) = 0x33; /*地址为0x00001000*/ ld文件flash_test_address 段默认从指定地址开始为其分配连续的地址,查看map文件,常量地址如下: 二进制bin文件0x1000信息如下; 2.3 定义多个不连续的常量 此时需要修改ld文件 .flash_test_address...
Timer interrupts (Interrupt ID #7) are triggered when the memory-mapped register mtime is greater than or equal to the global timebase register mtimecmp, and both registers are part of the CLINT memory map. mtimecmp can be written by other harts to set up timer interrupts. The mtime and ...
As shown in Table 1 [12], there are four sets of predefined custom instruction operation codes, and all the custom instructions in this article are defined under the custom-0 opcodes. Table 1. RISC-V base opcode map, inst[1 : 0] = 11. inst[4 : 2]000001010011100101110111...
The compressed instruction encodings are mostly common across RV32C, RV64C, and RV128C, but as shown in Table [rvcopcodemap], a few opcodes are used for different purposes depending on base ISA. For example, the wider address-space RV64C and RV128C variants require additional opcodes to...
htif_t::load_program() 中,std::map<std::string, uint64_t> symbols = load_payload(targs[0], &entry); 通过load_payload 程序读取了 elf 文件(load_payload 的原理暂不讨论)。从符号表中获取了 tohost_addr 和fromhost_addr。在这里建立起了模拟器与主机之间的关系,根据上面找到的取指指令 insn_...
