Consider an Intel 8086-based system with a 16-bit external data bus. The even bank is enabled by the signal _______ (which is active low), while the odd bank is enabled by the signal _______, which is active (low/high circle one). A word can be accessed in one memory access if the low byte is located at an (even/odd circle one) address. If not, two memory accesses would be required due to the word not being located properly, which is called _______. In fact, the cost of this is so high that the assembler and operating system will, if necessary, "stuff" an extra byte (called " _______ ") to marks sure that the word is properly located. Regardless, if the word is not located properly, the processor will handle the issue by (halting/petting a cat/generating an interrupt/placing a Chipotle order and calling it a night/skipping the instruction circle one). The technique of locating the bytes in a word as low byte first, followed by high byte, is called _______. This also implies that the address of the word is defined as the address of the (high byte/low byte circle one) in the word. The 8086's 6-byte long prefetch queue was a structure that aided processor performance as long as the instruction execution sequence was implemented (with for-next loops/circularly/random ly/linearly/using many branches circle one). Externally, the 8086 had a _______ address/data bus, which meant that the address signals and the data signals shared the same pins on the chip. This meant that the address had to be latched into external circuitry (before/after circle one the data was on the bus. To accomplish the latching, the 8086 (and 8088) had an additional pin, called _______ to allow the external circuitry to latch in the address. Upon reset, the CS register is loaded with _______ and the instruction pointer register is loaded with _______, for a real-mode physical address of _______ hex.
