Branch (computer science)
A branch is an instruction in a computer program that can cause a computer to begin executing a different instruction sequence and thus deviate from its default behavior of executing instructions in order.

Branch misprediction
Branch misprediction occurs when a central processing unit (CPU) mispredicts the next instruction to process in branch prediction, which is aimed at speeding up execution.

Branch predictor
In computer architecture, a branch predictor is a digital circuit that tries to guess which way a branch (e.g. an if–then–else structure) will go before this is known definitively.

Butler Lampson
Butler W. Lampson (born December 23, 1943) is an American computer scientist best known for his contributions to the development and implementation of distributed personal computing.

Cache (computing)
In computing, a cache, is a hardware or software component that stores data so future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation, or the duplicate of data stored elsewhere.

Cache prefetching
Cache prefetching is a technique used by computer processors to boost execution performance by fetching instructions or data from their original storage in slower memory to a faster local memory before it is actually needed (hence the term 'prefetch').

Central processing unit
A central processing unit (CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions.

Computer
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via computer programming.

Concurrency (computer science)
In computer science, concurrency refers to the ability of different parts or units of a program, algorithm, or problem to be executed out-of-order or in partial order, without affecting the final outcome.
New!!: Speculative execution and Concurrency (computer science) · See more »
Exponential growth
Exponential growth is exhibited when the rate of change—the change per instant or unit of time—of the value of a mathematical function is proportional to the function's current value, resulting in its value at any time being an exponential function of time, i.e., a function in which the time value is the exponent.

File system
In computing, a file system or filesystem controls how data is stored and retrieved.

Just-in-time compilation
In computing, just-in-time (JIT) compilation, (also dynamic translation or run-time compilation), is a way of executing computer code that involves compilation during execution of a program – at run time – rather than prior to execution.

Meltdown (security vulnerability)
Meltdown is a hardware vulnerability affecting Intel x86 microprocessors, IBM POWER processors, and some ARM-based microprocessors.

Memory dependence prediction
Memory dependence prediction is a technique, employed by high-performance out-of-order execution microprocessors that execute memory access operations (loads and stores) out of program order, to predict true dependencies between loads and stores at instruction execution time.

Microprocessor
A microprocessor is a computer processor that incorporates the functions of a central processing unit on a single integrated circuit (IC), or at most a few integrated circuits.

Out-of-order execution
In computer engineering, out-of-order execution (or more formally dynamic execution) is a paradigm used in most high-performance central processing units to make use of instruction cycles that would otherwise be wasted.
