The loop-switch sequence is a specific derivative of spaghetti code. It is not necessarily an antipattern to use a switch statement within a loop—it is only considered incorrect when used to model a known sequence of steps. The most common example of the correct use of a switch within a loop is an inversion of control such as
In the C programming language, Duff's device is a way of manually implementing loop unrolling by interleaving two syntactic constructs of C: the do-while loop and a switch statement. Its discovery is credited to Tom Duff in November 1983, when Duff was working for Lucasfilm and used it to speed up a real-time animation program.
Switch expressions are introduced in Java SE 12, 19 March 2019, as a preview feature. Here a whole switch expression can be used to return a value. There is also a new form of case label, case L-> where the right-hand-side is a single expression. This also prevents fall through and requires that cases are exhaustive.
I'm actually finding a practical use for JK flip flop ICs w/ async preset and clear (xx74xx76A) right now by using its preset to implement low-latency switch debouncing (the state changes immediately when the button is pressed regardless of any clock or microcontroller input reading capability) which then can be stable so it can be read and ...
Conditionals within the code result in the execution of different code paths on successive calls, based on the values of the state variables. Another typical response is to implement an explicit state machine in the form of a large and complex switch statement or via a goto statement, particularly a computed goto. Such implementations are ...
Another method of implementing a branch table is with an array of pointers from which the required function's address is retrieved. Originally known as transfer vector , this method is also more recently known under such different names as " dispatch table " or " virtual method table " but essentially performing exactly the same purpose.
Ground bounce may be reduced by placing a 10–30-ohm resistor in series to each of the switching outputs to limit the current flow during the gate switch. [ 1 ] See also
Designers can implement registers in a wide variety of ways, including: register files; standard SRAM; individual flip-flops; high-speed core memory; In addition to the "programmer-visible" registers that can be read and written with software, many chips have internal registers that are used for state machines and pipelining; for example ...
