The microprocessor contains arithmetic and logic unit (ALU)‚ Instruction decoder and control unit‚ Instruction register‚ Program counter (PC)‚ clock circuit (internal or external)‚ reset circuit (internal or external) and registers. But the microprocessor has no on chip I/O Ports‚ Timers ‚ Memory etc. For example‚ Intel 8085 is an 8-bit microprocessor and Intel 8086/8088 a 16-bit microprocessor. The block diagram of

Pick an administrative agency of either the federal or a state government. Find where the current and proposed regulation changes for that agency are located on the Internet (i.e.‚ the Federal Register or the State Administrative Agency website.) Regulations.gov is a good place to begin your research. Pick one proposed regulation change currently under consideration (if you find one that has already closed out but interests you‚ you can use that instead) and write the following regarding it: 1

1. INTRODUCTION Reduced instruction-set computers (RISC) are designed to have a small set of instructions that execute in short clock cycles‚ with a small number of cycles per instruction. RISC machines are optimized to achieve efficient pipelining of their instruction streams. The machine also serves as a starting point for developing architectural variants and a more robust instruction set Designers make high-level tradeoffs in selecting an architecture that serves an application

HAND GLOVE MOUSE here we designed and built a wireless computer pointing device with accelerometer based movement control. Our implementation allows the user to wear a set of hardware (a glove and connected armband) and control a cursor through different hand orientations and finger presses. Users can operate their computers with their hands in midair without the hassle of desks surfaces or wires. The motivation for this project was to create an intuitive glove-based pointing device for multiple
