 DSP processor. It allows the programmer to use up to 11 voices of sample playback at a 24kHz sampling rate plus a single channel of a custom ADPCM format.

The BSMT2000 was first used in 1991's Batman, and 2003's Terminator 3: Rise of the Machines is the last game to use the chip.

In 2003, due to the supply shortages of the BSMT chip, Stern added hardware emulation

Hardware emulation

In integrated circuit design, hardware emulation is the process of imitating the behavior of one or more pieces of hardware with another piece of hardware, typically a special purpose emulation system. The emulation model is usually based on RTL source code, which is compiled into the format...
