Check Bits

I need help figuring out the amount of check bits that are needed for a SEC code for an initial word size of 1024.

Computing Speedup & Efficiency

If I have 100 processors for a computation with 5% of the code cannot be parallelized, how do I compute the speedup and efficiency?

ARC subroutine that performs a swap operation

I need help writing an ARC subroutine that performs a swap operation on the 32-bit operands x=25 y=50 which are stored in memory. I need to use as few registers as possible. Thanks!! UPDATE: The ARC is a 32-bit machine with byte addressable memory. It can manipulate 32 bit data types, but all data is stored in memory as bytes, and the address of a 32 bit word is the address of its byte that has the lowest address.

8-word 32 bit RAM

I need to design an 8 word, 32bit RAM using 8x8 RAMs. Can you help? Thanks.

Storage on a disk with 2 surfaces

Background: I have a hard magnetic disk w/2 surfaces. The storage area on each surface has an inner radius of 1cm and and outer radius of 5cm. Each track holds the same number of bits even though the size differs from each other. The max storage density of the media is 10,000 bits/cm. The spacing between corresponding points on adjacent tracks is .1mm which includes the intertrack gap. The intersector gaps are negligible and that a track exists on the edge of the storage area. What is the max # of bits that can be stored on the disk and what is the data transfer rate from the disk to the head in bits per sec at a rotational speed of 3600 rpm? Thanks!!!
