In [computing](/source/Computing) ***Vector Pascal[1]*** is an [open-source](/source/Open-source) [compiler](/source/Compiler) implemented in [Java](/source/Java_(programming_language)) that extends the [Pascal](/source/Pascal_(programming_language)) programming language. It is designed to support efficient expression of algorithms using the SIMD model of computation. It imports into Pascal abstraction mechanisms derived from Iverson's [APL](/source/APL_(programming_language)) programming language. In particular it extends all operators to work on vectors of data. The type system is also extended to handle pixels and dimensional analysis.

## Supported architectures

- ARM64

- [Intel](/source/Intel) 486

- [Intel](/source/Intel) Xeon-Phi (auto parallelising Xeon Phi compile)

- [AMD](/source/Advanced_Micro_Devices) [Opteron](/source/Opteron) processor, the Opteron compiler supports multi-core parallelism

- [Pentium 4](/source/Pentium_4)

- [Athlon](/source/Athlon)

- [Sony](/source/Sony) [PlayStation 2](/source/PlayStation_2) Emotion Engine

- [The Cell processor](/source/Cell_(microprocessor)) (PS3)

- [Advanced Vector Extensions](/source/Advanced_Vector_Extensions) (Intel [Sandy Bridge](/source/Sandy_Bridge), AMD [Bulldozer (microarchitecture)](/source/Bulldozer_(microarchitecture)))

## Standards

The syntax generally follows that of [Turbo Pascal](/source/Turbo_Pascal) and includes all features of the ISO standard (ISO 7185-1990) except where overridden by Turbo Pascal. Features of Extended Pascal (an extended Pascal standard was created as ISO/IEC 10206) are also incorporated.
