DESCRIPTION:RISC-V E-Trace is a powerful tool for observing the execution o
 f a CPU. Optimizing code to use RISC-V Vector instructions brings novel ch
 allenges\, and gaining real-time insight into the code as it executes help
 s quickly iterate to better solutions. The ability of E-Trace to capture r
 untime "vector length" (vl CSR) and instruction execution\, together with 
 its very compressed nature makes it an ideal choice as a tracing format. T
 his keeps traces small\, allows live-streaming E-Trace data for post-proce
 ssing\, and ultimately allows the software developer to easily understand 
 the utilization of the vector unit. The end result is a very powerful work
 flow allowing fast iteration and development of low-level optimized softwa
 re\, with the execution of the code underpinned by QEMU and the RISC-V E-T
 race format.
