CodAL, standing for
Codasip Architectural Language, is central to developing a processor core using Codasip Studio. The language has a C-like syntax and it merges good practices and code constructs from conventional programming languages and hardware description languages. It has been developed from the outset to describe all aspects of a processor including both the instruction set architecture (ISA) and microarchitecture.
Each processor description includes four elements in its description:
Architectural resources, for example, registers and a program counter.
Instruction set, that is, names of instructions, their operands and their binary form (opcodes).
Semantics, or a description of the behaviour of each instruction and exception – how they affect the architectural resources.
