design a 32 bit counter that adds 4 at each clock edge the counter has reset and clock inputs upon reset the counter output is all 0
The counter is a digital sequencer, here a 4-bit counter. This simply means that you can count from 0 to 15 or vice versa depending on the counting direction (up/down).
The counter value (“count”) is evaluated on each positive (rising) edge of the clock cycle (“clk”).
If the "reset" input is logic high, the counter is set to zero.
If the "load" signal is logic high, the counter is loaded with the "data" input. Otherwise, count up or count down. If the "up_down" signal is logic high, the counter counts up, otherwise it counts down.

While working on the notebook computer, you noticed that the integrated Wi-Fi adapter is not working. 18 Click to view Windows 10 BACKGROUND It's not easy to find a definition of mobile device that everyone agrees on. However, many would agree on the following. They are Lightweight, usually less than two pounds, Small, designed to move with you in your hand or pocket), Touch or stylus interface; no keyboard or mouse. Sealed unit lacking any user-replaceable parts, Non-desktop Os; mobile devices that use special mobile operating systems and Device variants. Most modern mobile devices fall into one of a few categories: • Smartphones • Tablets Phablets Wearable technology Other mobile devices are purpose-built to be better at some task such as an e-reader.
As a junior IT professional, you have been asked to prepare the marketing director's iPad and notebook computer for an upcoming conference she is attending. In this scenario, it is important to ensure that both devices are in good working condition and that all necessary software and applications are installed and updated.
To troubleshoot the issue with the integrated Wi-Fi adapter on the notebook computer, you can try the following steps:
Check the device's Wi-Fi settings and ensure that the Wi-Fi adapter is turned on and the device is connected to the correct network.Restart the device and try connecting to the Wi-Fi network again.Check the device's Wi-Fi drivers and ensure that they are up to date. You can update the drivers through the device's manufacturer's website or by using a driver update tool.If the above steps do not resolve the issue, try resetting the device's network settings. This can be done through the device's settings menu.If the issue persists, you may need to contact the manufacturer or a professional repair service for further assistance.It is also important to ensure that the marketing director's iPad is fully charged and has all necessary applications and documents installed and updated for the conference. You should also make sure that the iPad is backed up to ensure that no important data is lost in case of any issues.

Virtual memory layout [20] You have a 64-bit machine and you bought 8GB of physical memory. Pages are 256KB. For all calculations, you must show your work to receive full credit. (a) [1] How many virtual pages do you have per process? (b) [1] How many bits are needed for the Virtual Page Number (VPN)? (Hint: use part (a)) (c) [1] How many physical pages do you have? (d) [1] How many bits are needed for the Physical Page Number (PPN)? (Hint: use part (c)) (e) [1] How big in bytes does a page table entry (PTE) need to be to hold a single PPN plus a valid bit? (f) [1] How big would a flat page table be for a single process, assuming PTEs are the size computed in part (e)? (g) [10] Why does the answer above suggest that a "flat page table" isn't going to work for a 64-bit system like this? Research the concept of a multi-level page table, and briefly define it here. Why could such a data structure be much smaller than a flat page table? (h) [4] Does a TLB miss always lead to a page fault? Why or why not?
We have 2^48 pages per person. The number of physical pages is 2^16.. 48 bits of VPN are mapped to 16 bits of PPN. The PTE size is 2B. The page table size is 2^49 B.
What are the steps to calculate pages per person, physical pages, VPN ,PTE size and the table size?We know that;
Virtual Address = 64bits
Virtual Address Space = 2^Virtual Address = 2^64B
Physical Address Space = 4GB = 4 X 2^30 B = 2^32 B
Physical Address = log_2(Physical Address Space ) = log_2(2^32)
= 32 * log_2(2) = 32 bits.
Page size = 64KB =2^16 B
a) No of Virtual Pages = Virutal Address Space/PageSize
= 2^64B / 2^16 B = 2^48
b) NoOfPhysicalPages = PhysicalAddressSpace/PageSize
= 2^32 B / 2^16 B = 2^16
c) VPN (in Bits) = log_2(NoOfVirtual Pages) = log_2(2^48) = 48
PPN(inBits)=log_2(NoOfPhysicalPages)= log_2(2^16) = 16
Thus 48 bits of VPN are mapped to 16 bits of PPN.
d) PTE( Page Table Entry) holds the Physical Page Number of given Virtual Page along with many information about the page.
PTEsize = PPN(inBits) = 16 bits = 2B
e) Flat page table is single level page table. A page table contains the Physical Page number for a given page number. It helps in the translation of Vitual Address to Physical Address.
PageTableSize = NoOfVirtualPages*PTEsize = 2^{48}*2B = 2^49
