Titre / Title: MicA, a micro-programming language for Rapid-2
Abstract : This document gives information about the way to use MicA - the Micro-Assembler available with the Rapid-2 system. Even though the second part of this paper may be considered as a user-manual (indeed, it has been done on purpose), the first part presents the Rapid-2 system with no technical hardware detail that would have been useless for the programmer.
Rapid-2 is a board intended to be connected to a host-computer. It offers massive parallelism and thus calculation power that speed up long tasks such as genetic sequence comparison, text processing, dictionary search and so forth. The application to be speed up has to be written for the board. MicA is the software tool that generates the binary code for the board, from a textual assembler-like program.
MicA is delivered with the Rapid-2 board, and so does L1 - the high level language dedicated to Rapid. First applications to Rapid have been written directly in MicA. However, since L1 is available the normal way to write an application is to use the high-level language that generates a MicA syntax file and then a binary file. MicA may be useful for controlling the L1 compiling coherency, or for patching L1 output. It offers possibilities to manually optimize some parts of the generated code that require particular execution time efficiency.
