2.5 HARDWARE IMPLEMENTATION. The following is a summary of the SMARTDOT module's hardware configuration and an overview of the hardware theory of operation. A working prototype of the SMARTDOT sensor module (based on this hardware configuration) has been used under real-world conditions (placed in a ball and rolled down the lane) for a total of about 500 frames (~50 games). 2.5.1 Hardware Configuration A summary of the major hardware components and their respective features is given below. See Figure 2-3 for a block diagram of the prototype SMARTDOT module. Microprocessor - Phillips 87C752 [21] • Intel 8051-based core. • Crystal Frequency - 3.6864 MHz (3.26 µsec instruction cycle). • 64 bytes on-board RAM (including general purpose registers and stack space). • 2 Kbytes on-board program EPROM. • 8-bit Analog-to-Digital Converter (130 µsec conversion time @ 3.6864 MHz). • 16-bit auto reload timer. • Additional fixed timer (300 Hz @ 3.6864 MHz). • Interrupts (timers, external, ADC). • Idle mode. Light Sensor - TAOS TSL251 Light-to-Voltage Converter [23] • Output: 60 mV/(µW/cm 2 ), 7.5 µsec rise/fall time. Memory - Microchip 24C04 Serial I 2 C EEPROM (4096 bits, 512 x 8) [20] • 8 byte page write. • 10 msec maximum write time per page. • 400 kHz maximum clock rate. Amp Sensors Piezoelectric Film Sensor [19] • Responds to changes in pressure. Maxim MAX931 Ultra-Low Power Comparator [18] • Current draw:
