Internal Translator

(language, mathematics)

(IT) An early compiler for mathematics developed by A.J. Perlis et al at Carnegie Tech ca 1957. IT was originally written for the Burroughs 205, then the IBM 650.

IT was the forerunner of RUNCIBLE, GATE, CORRELATE and GAT. IT source code was converted to PIT, thence to SPIT.

IT-2 produced machine language directly, IT-3 developed at Carnegie added double-precision floating-point.

Sanken's SLA7O5lM has an internal translator for full, half-step or rotating direction, inputs compatible with 3.3V or 5.0V control signals, a sleep-mode function suitable for applications that require a stand-by mode and synchronous pulse-width modulation (PWM) operation for two-phase outputs to eliminate the motor vibration at hold mode.
