Inuit snow goggles function by reducing exposure to sunlight, not by reducing its intensity It is important to note that dark glasses that do not block UV radiation can be more damaging to the eyes than not wearing eye protection at all, since they tend to open the pupil and allow more UV rays into the eye.

Their usage is mandatory immediately after some surgical procedures, such as LASIK, and recommended for a certain time period in dusty areas, when leaving the house and in front of a TV screen or computer monitor after LASEK. The American Optometric Association recommends wearing sunglasses that block ultraviolet radiation (UV) whenever a person is in the sunlight to protect the eyes from UV and blue light, which can cause several serious eye problems.
Since the 1930s, sunglasses have been a popular fashion accessory, especially on the beach. In the early 20th century, they were also known as sun cheaters ( cheaters then being an American slang term for glasses). They can sometimes also function as a visual aid, as variously termed spectacles or glasses exist, featuring lenses that are colored, polarized or darkened. Sunglasses or sun glasses (informally called shades or sunnies more names below) are a form of protective eyewear designed primarily to prevent bright sunlight and high-energy visible light from damaging or discomforting the eyes. The data memory SRAM for the file register in the PIC microcontroller is 8 bit and like program ROM, it is a byte addressable.Wearing sunglasses under direct sunlight: Large lenses offer good protection, but broad temple arms are also needed against "stray light" from the sides. The PIC16 ROM is 14 bit, while the PIC12 has a 12 bit width. Not all the program ROMs in the PIC microcontrollers have 16 bit width. This is the part of the RISC architectural philosophy. The PIC designers have made all instructions either 2 byte or 4 byte there are no 1 byte or 3 byte instructions, as in the case with the x chips. That will make instruction fetch a single cycle. This way, the CPU brings in an instruction from ROM every time it makes a trip to the program ROM.

Another reason to male the code ROM 16 bits wide is to match it with the instructions width of the PIC18 because the vast majority of the instructions are 2-byte instructions. The widening of the data path between the program ROM and the CPU is another way in which the PIC designers increased the processing power of the PIC18 family.
The same rule applies to the entire program address space of PIC18, which is 2M, organized as 1M X 16. The 64K ROM space is shown as 32K X 16 using a 16-bit word data size. Program ROM Width for in PIC18 microcontroller The more lanes, the more information we can bring into the CPU for processing.įor the PIC18, the internal data bus between the code ROM space and the CPU is 16 bits as shown below. The data bus is like traffic lanes on the high way where each lane is 8 bits wide.

To increase performance even further, Intel corporation increased data bus width to 32 bits for the 386 and 64 bits for the Pentium. To bring in more information, code or data, into the CPU, increasing the width of the data bus to 16 bits. CPU's with 8-bit data will fetch one byte at a time. If we have 16 address lines, it will give us 2 16 locations, which is 64K of memory space with an address map of 0000 - FFFFH. Each location of the address space holds only one byte. A microprocessor's memory that holds code is byte-addressable and under the control of the program counter.
