Running at 1 Million Instructions Per Second?

Humanoido

The BS1 PIC chip is rated at one million instructions per second (machine language).
According to specs, PBASIC runs at 2000 Instructions Per Second.

Is there a way to access BS1 machine language, bypass PBASIC loading,
and run a few machine language instructions at 1 million IPS?

Only if you replace the BS1 chip with a compatible PIC. You'll lose the BASIC interpreter, of course.

The BS1 is a pic chip. So there must be some way to access
the machine language side of it before downloading pbasic,
without actually replacing the chip. I only need to access an
instruction or two to make an example. Thanks sincerely.

No, what you are proposing is simply not possible. The PBASIC byte code interpreter is burned into non-voltile memory (EEPROM or OTP EPROM). Machine code has to reside in that memory (not RAM) to execute, so any machine code you execute would have to replace portions of the PBASIC interpreter, rendering the chip unusable as a BASIC Stamp. In the case of OTP EPROM, your only option, as Leon explained, is to replace the chip.

It's not possible to program a BS1 with machine language. The PIC chip on the BS1 has been programmed with the PBASIC interpreter by Parallax.

Just use a PIC on its own if you need a lot of performance. The 16-bit PICs can do 40 MIPS.
