• Digital Signal Processing, Digital Video coding, Digital Image Processing
• Other subjects like Advance Electronics, CMOS mixed signal Design, VHDL.

PROJECTS

• Device Control using PC commands: Control devices like LAMP brightness, motor speed, and speaker tone using DMX512 communication on PIC18f4431 controller. Communication protocols used are RS232, DMX512. Write the commands on HyperTerminal and control the devices at the other end of Microcontroller.
• Co-operative RTOS: C code for the 18F4520 controller that implements a cooperative RTOS with support for semaphores, system timers, and priority scheduling.
• 32bit microprocessor design: Designed 32 bit pipelined microprocessor blocks starting from Instruction fetch, Instruction decode, fetch operand, execution block and write back block.
• Cache memory design: Determine the best architecture for the 256 kb cache including type (set-assoc or direct), nway (if set-assoc), number of cache lines, block size, and write strategy (write-back or write-through).Assumed that the DRAM data bus is limited to 64 bits in width. The code was written in VC.
• Wireless Mesh Network with Ethernet bridge controller: Build hardware and developsoftware for a wireless mesh network and controller. The software developed includes a real-time operating system, device driver, protocol stacks, and application layer software for a controller and device nodes in ISM-band wireless mesh network. The wireless network controller will bridge to an 802.3/Ethernet 10BASE-T network with a HTTP interface.
• Design of Digital Communication system: Design of physical layer simulation(using MATLAB) reference system for a digital communication system, a fixed wireless local area network(WLAN). Design includes BPSK modulation, Up sampling, channel coding at the transmitter side and Down sampling, channel equalizer design (MLSE and MDD) at the receiver side. Plot the Bit Error Rate and compare the performance of the system.
