How do you write a VHDL code for this

The SecondGenerator block generates the second count i.e; it increments an internal variable once every second from 0 to 59 and then rolls back to 0. That (std_logic_vector) variable can be assigned to a (std_logic_vector) signal second[5..0] which comes out of the block. Note that this is a 6-bit std_logic_vector value because counts up to 59 can be accommodated in 6 binary digits (26 = 64). As most clocks do not display second counts so this value is not utilized any further here. This block also generates a pulse every time the second counter rolls over i.e. every 1 minute. This comes out as the std_logic signal minute_out .

Let x[n] = cos(17?n 64 ) + 2sin(23?n 32 ) for 0 ? n ? 255, and 0 otherwise. The signal x[n] is passed through an LTI system with transfer function H(z) = (1? 1 2z?1)(1? 1 3z?1). Denote the signal at the output of the system by y[n]. We want to recover x[n] by passing y[n] through an inverse system.

Write a PLC ladder program to describe an application consisting of keeping constant the level of fluid in a fluid tank – if the level goes below a minimum, the fluid enters into the tank, and if the level goes above a maximum, inlet stops.

Based on research on the digital light processor (DLP) chips. DLP chips have only been in production for several years, yet their manufacturer claims a "10-year plus" lifetime. These chips are micro-mirrors that move as much as 15 degrees, three times during a TV frame.

Question: Explain how the manufacturer could make such a claim when no one has had the chip for more than 4 years.

In the PIC18F452 Programming Model, list 2 registers that are used to access the Program Memory. Indicate their sizes.
