CS343 Midterm Test Fall2017 Name: 1 Generally anodem microcontoler uses A only RAMS B only DRAM C. only Flash ROM D. both RAM and ROM A an 8-bit address bus B an 8-bit data bus C only 8-bit conterol signals D an 8-bit program counters negister 3. For the 8051 microcontroller, the lowest 8 bytes of on board RAM are A Bank 0 8 Bank 1 C Bank 2 D Bank 3 4 Which of the following 8051 registers contains the address of the next instruction to be executed? A. A B RO-R7 D.Program counter 5 Which of the following is actually stored in on-chip program memory? A. The hex object codes of the application program B. The assembly source fSles of the application program C C codes of the application program D Java codes of the application program 5. What is the maximum number of memory locations (bytes) that can be accessed by an address bus that is 18 bits wide? A 8 8. 64 C. 64K D BKExplanation / Answer
1.
D
both Ram and Rom
Program memory in the form of NOR flash or OTP ROM is also often included on chip, as well as a typically small amount of RAM. Microcontrollers are designed for embedded applications, in contrast to the microprocessors used in personal computers or other general purpose applications.
2.
A.
An 8-bit microcontroller uses an 8-bit address bus
3.
8051 Micro controller is 8-bit controller.it contain 128Byte of internal RAM.internal RAM divided into three section.
The lowest 8 bytes on board ram are Bank 0.
4.
D
Program Counter always contains an address and it is the address of the next instruction that is to be executed..
