PURPOSE:To eliminate the need of extending a different bus between other modules by constituting the system so that in the case a microprocessor reads out data from a memory, a bus can be allocated to other module after sending out an address to the bus. CONSTITUTION:A system bus controller...
Control bus 4. System bus. The data bus is responsible of transferring data of PLC. A PLC data bus that can carry maximum of 8-bit length are called 8-bit data bus, and the microprocessor of such a PLC is termed as 8-bit microprocessor. Such a microprocessor performs only 8-bit opera...

The slave address field is a 7-bit value that is different for each DSP device. Vendors who license the I2C bus are assigned address ranges for their devices, and the ADAU1701 is 00110100, or 0x34. There is a built-in library called Wire that makes simple I2C communication fairly easy....
The process control instrument includes a microprocessor operating in accordance with the SPI data bus protocol, first and second peripheral devices, and a data bus coupled to the microprocessor and the first and second peripheral devices. The improved data bus protocol used in the process control ...
PLDs can be used to replace TTL glue in microprocessor-c⋏sed designs. This application note from Advanced Micro Devices shows how two PLD-based VME interface controllers — a bus arbitter and an interrupt handler — can be developedAccess through your organization Check access to the full tex...

Its external memory bus was put to good use in interfacing with the memory-mapped array of 64 PWM registers (i.e., 32 × 16 bits) inside the FPGA. The many roles of the MCU include initializing the FPGA registers with user-configurable servo startup positions stored in the internal ...
