You have DDR2 memory with a CAS latency of 6 and DDR3 memory with a CAS latency of 7. What can you tell about the relative speed of the two memory modules?
In 32-bit mode, which registers can be used in a base-index operand?
We want to use a single ROM as a lookup table that can perform two
bitwise operations, XOR and NAND. There are two operands with each
operand being 4 bits (X3X2X1 Xo and Y3Y2Y1Y0), and a selector (S) for
the operation chosen.
