With VLSI Technology Inc. as its silicon partner, ARM came up with ARM1, the first ARM silicon on April 26, 1985, which was used as a second processor to the BBC Micro to develop the simulation software to finish work on the support chips (VIDC, IOC and MEMC) and to increase the operating speed of the CAD software used in development of … Introduction to ARM processor. 3 Why ARM here?
This type of portability and compatibility is the foundation of the Arm ecosystem. Arm CPU architecture is a set of specifications that allows developers to write software and firmware that will behave in a consistent way on all Arm-based processors. 2 Brief History of ARM • ARM is short for Advanced Risc Machines Ltd. • Founded 1990, owned by Acorn, Apple and VLSI • Known as computer manufacturer before becoming ARM • Acorn developed a 32-bit RISC processor for it’s own use Acorn Archimedes. ARM architecture is highly modular: the only mandatory component of an ARM processor is the integer pipeline; all other components, including caches, MMU, floating point and other co-processors are optional, which gives a lot of flexibility in building application-specific ARM-based processors. ARM architecture R15 being the program counter Orthogonality says you can do lots of wacky things using the PC On a simple implementation, the apparent orthogonality is cheap ARM architecture has “shifts with all data processing” Orthogonality from original ARM1 pipeline But the behaviour has to be maintained into the future The Arm CPU architecture allows developers to write software and firmware that conforms to the Arm specifications, secure in the knowledge that any Arm-based processor will execute it in the same way.
