Concept explainers

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.

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?
For simplicity, let us assume that each instruction on a RISC processor is executed in 2 microseconds and that an I/O device can only wait for an interrupt to be handled for a maximum of 1 millisecond before it is serviced. Do you know how many instructions may be executed with interrupts deactivated before they reach a specific number of instructions?
How many conductors are necessary for an address bus to have if it has to be able to address eight different devices? What happens if every single one of those components also has to be able to communicate with the I/O control device?
We pointed out that I/O buses do not need separate addresslines. Construct a timing diagram similar to Figure 7.11 thatdescribes the handshake between an I/O controller and a diskcontroller for a write operation. (Hint: You will need to add acontrol signal.)
When discussing data transfer, one of the most important questions to ask is how the width or length of a bus can affect or have an effect on the architecture of a computer system. Provide evidence to back up the assertions you're making.
A system bus transports data between two or more system components. Because an 8-bit CPU only has 8 data bits, it cannot be directly linked to each and every Input / Output (I/O) device. Describe how all of the devices will be able to interact throughout a single machine cycle (if possible).
Imagine I had a memory with 256 memory cells arranged in a grid 8 columns wide and 32 rows tall. Further, imagine that I want to fetch the value at memory address 7, so I send the bits 00000111 to the MAR and a "fetch" signal to the Fetch/Store controller via the system bus. Explain the rest of this fetch process. Be specific in terms of what bits will be sent to the decoders and what they will do with those inputs. Typed answer only
When comparing serial and parallel bus data transfer, what are the advantages of the former? Are there any disadvantages to employing a serial bus as opposed to a parallel bus?
Because of this, maintaining synchronization between the performance of the bus, the CPU, and the memory is almost impossible.It is crucial to recognize and comprehend these problems, as well as how it is challenging to keep these machines in balance as a result of their nature.
