Write a brief algorithm for the above program (3 marks) (3 marks) (2marks). The following is the assembly language using DAC to interface with 8255 and generate a square wave on CRO. A DAC is a Digital to Analog converter that takes the digital information from a device and converts it into an analog signal that can be played back by an audio system. Explain the 8086 bit manipulation instruction with an example of each. When it comes to recording in your studio set up at home, be it for music, podcasts, streaming, voiceovers, or any other content production, USB microphones are a great place to start. In cascade mode one 8259 is configured in Master mode and other should be configured in the Slave mode. 2003-2022 Chegg Inc. All rights reserved. An audio interface simply has more tools for the music producer than a DAC. It will open you up to a variety of new options when youre recording, including layering. This process records your instrument at a high quality. If the INTR interrupt is enabled, the 8086 will go through its INTR interrupt procedure and sends out two INTA pulses to both the master and the slave. 8. Each slave 8259 is identified by the number which is assigned as a part of its initialization. Active volcanoes around the world Here are spectacular pictures of some active volcanoes around the world. These devices provide good sound quality although not much more. IF data =00H [00000000], Vref= 10V Therefore, V0= 0 Volts. By accepting, you agree to the updated privacy policy. The USP of the NPTEL courses is its flexibility. Exists only to promote a product or service. A typical audio interface will also contain two volume controls. An Audio Interface converts analog sound into digital sound, recorded in 1s and 0s (also known as binary code). Its also an excellent tool for podcasts and audiobook recordings. margin-left: -0px; It consists of three 8-bit bidirectional I/O ports i.e. When the slave receives an interrupt signal on one of its IR inputs, it checks mask condition and priority of the interrupt request. } Sending the 3-bit ID number enables the slave. analog signal a Digital-to-Analog Converter. As we are using single 8259 in the system SP/EN pin is tied high and CAS0-CAS2 lines are left open. But, how does it differ from DAC? Describe the action taken by 8086 when INTR pin is activated. Configure write (WR) signal low. E, RW and RS. Its interfacing can be done using a port device or latch. off.

A decoder 74LS138 is to interface with 8086 microprocessor and a memory for perfect communication. Each 8259A has its own addresses so that command words can be written to it and status bytes read from it. These cascaded 8259s are referred as slave. If that IR input of the master is unmasked and if that input is a higher priority than any other IR inputs currently being serviced, then the master will send an INT signal to the 8086 INTR input. } To produce the best quality possible when playing or producing music, youll need great equipment. Youll get better quality sound for your money than an audio interface could give you because a DAC has only one job. Therefore I to V converter is used to convert analog output current of DAC to equivalent analog voltage. we will use a Potentiometer to vary the voltage.
