If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?
Most Intel CPUs use the __________, in which each memory address is represented by two integers.
When a signal is received, the CPU suspends its current activity to process the request. The technique used in this instance is: A' Signal of Interrupt Spooling B C' Interrupt Handling D Polling.
Whenever the CPU receives a signal, it stops whatever it is doing to deal with the incoming request. So, here's how the mechanism operates: Spooling with B as the interrupt signal C as the interrupt handler D as the polling method A'.
2. There are interrupt in 8086 Mp, user, starting from interrupt number_ of them are available for the 3. IVT is a table that contain the of ISR of each interrupt. The size of the table is 4. The low bank (even bank) in 8086Mp memory has a size of bytes, starting from address: and ending with address:_
Assume that an interrupt mechanism uses the hardware stack to store PC and other registers of the interrupted computations. The interrupt mechanism recognizes 4 interrupt vectors IV [1], IV [2], IV [3], IV [4] initialized by addresses of their corresponding ISRI=1.4. The elements of the hardware stack are a record R, where each field stores a specific CPU register (R.PC is the field, which stores the program counter PC and so on). The Hardware stack is manipulated using the standard stack operation Pop, Push, EmptyStack. a) Explain how the CPU detects an interrupt signal I and what actions should be taken ? b) Write the initial and final sequences of instruction of a given ISR I. (Transparency). c) Write the ISR4 such that whatever number of interrupted computation (in the stack) it gives the control to the first one interrupted.
A BCD number between 0 and 99 is stored in an R/W memory location called the Input Buffer (INBUF). Write a main program and a conversion subroutine (BCDBIN) to con- vert the BCD number into its equivalent binary number. Store the result in a memory lo- cation defined as the Output Buffer (OUTBUF).
Is there a connection between interrupt latency and the time it takes to switch contexts?

In computer architecture, SIMD may refer to the situation where. a) multiple CPU cores can access the same memory concurrently. b) the same operation can be applied to multiple operands with only a single instruction. c) multiple independent instructions can be executed at the same time in the same CPU core. d) multiple independent memory banks show up as a single address space.
Q1- Write a program in assembly language for the 8085 microprocessor to send 10 bytes of data located at the memory address (3000H to 3009H) using SOD at a baud rate of 1200. Information: The 8085 processor operates at a frequency of 3.072 MHz. When sending each of the required bytes, you must adhere to the following: The two high bits of the start bits must be sent, after that the data bits are sent, after that the low bit of the stop bit is sent. The following flowchart will help you, but you should notice that this flowchart deals with one byte, and you are required to deal with 10 bytes. The solution must be integrated and include the calculation of the baudrate delay time Transmit No Set up Character Bit Counter Send Start Bit Wait Bit Time Get Character in Accumulator Output Bit Using Do Wait Bit Time Rotate Next Bit in Do Decrement Bit Counter Is It Last Bit? Yes Add Parity if Necessary • Send Two Stop Bits Return (a)
