Memory chips are integrated circuits that are capable of storing information. Today, memory chips are on various types of RAM, like DRAM, EPROM, EEPROM, and SRAM. Memory chips can also be integrated into hardware devices, like a video card. The first memory chip to utilize wires, in the form of a grid, for addressing memory cores was invented by Jay Forrester in 1949. However, Forrester’s electronic wire memory chip wasn’t actually developed until around 1953....

Memory dependence prediction, also known as speculative load, is a prediction technique used by modern CPUs. In this method, the processor tries to forecast operations that depend on accessing the same data in a computer’s memory, and executes those operations out of order to improve performance. By executing memory-dependent operations in an order other than that implied by the program, the system can avoid an occurrence known as a RAW (read-after-write) dependency violation....

An intermediate language is an abstract programming language used by a compiler as an in-between step when translating a computer program into machine code. Before compiling the program into code for an actual, physical machine, the compiler first translates it into intermediate code suitable for a theoretical, abstract machine. This code is analyzed, and if any opportunities for optimization are identified, the compiler can perform them when performing the translation into assembly language....
