Namespace std::bit This namespace contains bit-manipulation functions that can make the ACT description more legible. export template function repeat(int x) : int; This concatenates N copies of the W-bit input x to create an output of width

Namespace std::channel This contains standard names for commonly used asynchronous channels. A channel has two ends: the sender and receiver. In the wire-level handshake protocol, the end that initiates the communication is referred to an the active

Namespace std::data This namespace contains standard names for commonly used data encodings in asynchronous circuits. template deftype d1of <: enum (bool?! d[N]); This data-type specifies a one-of-N encoding (a.k.a. a one-hot encoded value). The all zero/false state is used to indicate an neutral value (i.e. the absence of data). The

Namespace std::gates The namespace std::gates contains a collection of gates that are commonly used in digital design. export template defproc ortree (bool? in[N]; bool out); This is an N-input OR tree constructed using a mixture of two and three input gates. If the

Namespace std The std namespace contains a collection of standard definitions for channels, data types, and other components. This can be viewed as ACT's equivalent of the C++ standard template library. Functions Parameter-type functions export function max(pint a, b) : pint;
