RISC-V Matrix Multiplication Extension Specification v0.3.0

RISC-V Matrix Multiplication Extension Specification v0.3.0
Update log compared to v0.1.0：

• Add widen floating-point matrix multiplication instructions for mixed precision

• Add move instruction between scalar registers and matrix registers for debug purpose

• Change mrelease to initial ms status/add mzero for security issues

• Remove streaming memory access instruction, Compatible with zhintntl extensions instead of customizing hint operations in extensions

• Support new data types int4/bf16

• Add RLEN, modify MLEN definition for a clearer programming model

• Reorganize the matrix CSR to be more accurate and meet the RISC-V standards

• Modify arithmetic instructions opcode, more consistent with RISC-V coding habits

• New intrinsic style with function overloading
