The introduction talks about how DSP is important, and how this extension makes RISC-V faster and more efficient on DSP tasks.

Should there not be some words about how P does this by implementing SIMD operations on the existing integer X registers? Assuming that is what it does. I thought it was, but I can't find anything telling me that.

Hi Bruce,

You are absolutely right. This is a great suggestion and we will highlight P-ext implements SIMD operations on X registers in the introduction of the next revision.
