Hi, I recently saw the new instruction counter, and wanted to know which unit handles Narrow instructions : FMA, CVT or SFU?
All of them =)
This counter is intended to give developers feedback about how well their shaders are using mediump/relaxed precision. It increments for every 8-bit and 16-bit instruction executed, no matter which pipe it executes in.
You can compute the percentage of narrow instructions as "narrow / (FMA + CVT + SFU)".
Thank you Pete!
