Slow Level 1/2 BLAS on device DSP

[Cstandardlib]

Details

Known issues:
DSP MTBLAS library does NOT have optimized Level 1/2 BLAS operators.
It is recommended that on DSP device, BLAS except gemm should use CPU instances instead of DSP ones.

Task list for Issue attackers (only for developers)

• Reproduce the performance issue on a similar system or environment.
• Identify the specific section of the code causing the performance issue.
• Investigate the issue and determine the root cause.
• Research best practices and potential solutions for the identified performance issue.
• Implement the chosen solution to address the performance issue.
• Test the implemented solution to ensure it improves performance without introducing new issues.
• Optimize the solution if necessary, considering trade-offs between performance and other factors (e.g., code complexity, readability, maintainability).
• Review and incorporate any relevant feedback from users or developers.
• Merge the improved solution into the main codebase and notify the issue reporter.
