TDA4VL-Q1: C7X Compiler: Division operation is not performed as vector operation but only as scalar operation

TDA4VL-Q1: C7X Compiler PC Build

Part Number: TDA4VL-Q1

Tool/software:

Hello TI

My C7X application has SIMD instructions and functions. And the runtime is around 25ms in EVM/ECU
But the same code runs around 6000ms in PC build(Linux Build)

I know that PC Build binary in Linux will be slower than C7X binary and cannot be compared for performance.
But runtime difference is 6000ms(PC Binary) and 25ms(C7X Binary). The difference is too huge. Its around 24000 % increase in runtime.
Is this an expected behavior in PC build ?

One of our customers expects PC runtime to be within 600 % of C7X runtime. Is this possible to achieve by any TI setup ?

Thanks
