Examples of, and arguments for, Jump Tables via Function Pointer Arrays in C/C++; Example code generated by 'Switch/Case' branch table in C, versus IF/ELSE. Example code generated for array indexing if structure size is divisible by powers of 2 or otherwise. "Arrays of Pointers to Functions" by Nigel Jones
A system bus is a single computer bus that connects the major components of a computer system, combining the functions of a data bus to carry information, an address bus to determine where it should be sent or read from, and a control bus to determine its operation. The technique was developed to reduce costs and improve modularity, and ...
Control tables reduce the need for programming similar structures or program statements over and over again. The two-dimensional nature of most tables makes them easier to view and update than the one-dimensional nature of program code. In some cases, non-programmers can be assigned to maintain the content of control tables.
The Simple Bus Architecture [1] (SBA) is a form of computer architecture. It is made up software tools and intellectual property cores ( IP core ) interconnected by buses using simple and clear rules, that allow the implementation of an embedded system ( SoC ).
A data path is the ALU, the set of registers, and the CPU's internal bus(es) that allow data to flow between them. [2] A microarchitecture data path organized around a single bus. The simplest design for a CPU uses one common internal bus. Efficient addition requires a slightly more complicated three-internal-bus structure. [3]
Multibus supported multi-master functionality that allowed it to share the Multibus with multiple processors and other DMA devices. [ 6 ] The standard Multibus form factor was a 12-inch-wide (300 mm), 6.75-inch-deep (171 mm) circuit board with two ejection levers on the front edge.
Multiway branch is the change to a program's control flow based upon a value matching a selected criteria. It is a form of conditional statement.A multiway branch is often the most efficient method of passing control to one of a set of program labels, especially if an index has been created beforehand from the raw data.
The ccTalk multidrop bus protocol uses an 8 bit TTL-level asynchronous serial protocol. It uses address randomization to allow multiple similar devices on the bus (after randomisation the devices can be distinguished by their serial number). ccTalk was developed by CoinControls, but is used by multiple vendors.
