A direct-mapped cache consists of 8 blocks. Byte-addressable main memory contains 4K blocks of 8 bytes each. Access time for the cache is 22ns, and the time required to fill a cache slot from main memory is 300ns. (This time allows us to determine the block is missing and bring it into cache.) Assume a request is always started in parallel to both cache and to main memory(so if it is not found in cache, we do not have to...

Assume that 20 bytes of Packed BCD data is present in a data memory at location 0x300 to 0x313. You have to write an assembly program that will display data on a two seven segment displays one connected to Port A and other connected to Port B using loops. You also have to analyze data if the data is equal to 0x22 then start storing data bytes at corresponding memory address 0x400 to 0x413 in reverse order i.e. if the...
