The real problem is that the 8086 was a 16 bit processor, with 16 bit registers and 16 bit addresses. This limited the processor to addressing 64K chunks of memory. Intel's clever use of segmentation extended this to one megabyte, but addressing more than 64K at one time takes some ...

The original8086had 16-bit registers and its instructions used mostly 8-bit or 16-bit operands. This allowed code to work with 216 bytes, or 64K of memory, yet Intel engineers were keen on letting the CPU use more memory without expanding the size of registers and instructions. So they in...
In the specific case the adder generates a 24 bit address word to increase memory addressing capacity from the original 20 bit value. The value are multiplexed to the read/write memory. ADVANTAGE - Uses data bits to expand address capacity.POLLY EDGAR DIPL ING...
Examples of chips applying this scheme are the Intel 8086 and the Hitachi H8/500. The idea of segmented memory addressing is fairly simple. Addresses are divided into two parts: a segment number and an offset. Offsets (usually 16 bits) are used most of the time, where the additional high...

In Linux, only 3 segment descriptors are used during boot. They are defined with theGDT_ENTRYmacro and stored in theboot_gdtarray. Two of the segments are flat, addressing the entire 32-bit space: a code segment loaded into cs and a data segment loaded into the other segment registers. ...

One address is placed in the AGP request queue on each rising clock edge while PIPE# is asserted. When PIPE# is deasserted no new requests are queued across the AD bus. During SBA Operation: This signal is not used if SBA (Side Band Addressing) is selected. During FRAME# Ope...
