Abstract :
Two peripherals for digital signal processor (DSP) based servomotor controllers implemented using programmable gate arrays (PGA) are presented. The first is a 32 bit quadrature decoder capable of an input bandwidth of 40 MHz and outputs its counter results as signed integers. The second is an 11 bit amplifier (10 bits plus sign) with an update rate of 80 kHz, which also accepts signed integers
