In computer architecture, a delay slot is an instruction slot being executed without the effects of a preceding instruction. [1] The most common form is a single arbitrary instruction located immediately after a branch instruction on a RISC or DSP architecture; this instruction will execute even if the preceding branch is taken.
S88, shorthand for ANSI/ISA88, is a standard addressing batch process control. It is a design philosophy for describing equipment and procedures. It is not a standard for software and is equally applicable to manual processes. It was approved by the ISA in 1995 and updated in 2010. Its original version was adopted by the IEC in 1997 as IEC 61512-1.
Reducing the delay of a wire by cutting it in half and inserting a repeater is known as repeater insertion. The cost of this procedure is the additional new delay through the repeater itself, plus power cost because the repeater is an active circuit that must be powered, whereas the plain unrepeated wire was originally an unpowered passive ...
An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing.
The delay locked loop is a variable delay line whose delay is locked to the duration of the period of a reference clock. Depending on the signal processing element in the loop (a flat amplifier or an integrator), the DLL loop can be of 0th order type 0 or of 1st order type 1.
Electronic design automation is used extensively to ensure that designers do not violate design rules; a process called design rule checking (DRC). DRC is a major step during physical verification signoff on the design, which also involves LVS ( layout versus schematic ) checks, XOR checks, ERC ( electrical rule check ), and antenna checks.

The following is two executions of the same four instructions through a 4-stage pipeline but, for whatever reason, a delay in fetching of the purple instruction in cycle #2 leads to a bubble being created delaying all instructions after it as well.
