To achieve the same computation on the SPU might require that an entirely different algorithm be written from scratch. The most important conceptual similarity between VMX and the SPU architecture is supporting the same vectorization model. For this reason, most algorithms adapted to Altivec will usually adapt successfully to the SPU ...
The permute unit is closely associated with memory instructions as it serves to pack and unpack data structures located in memory into the SIMD multiple operand format that the SPU computes on most efficiently. Unlike other processor designs providing distinct execution pipes, each SPU instruction can only dispatch on one designated pipe.
The first documented computer architecture was in the correspondence between Charles Babbage and Ada Lovelace, describing the analytical engine.While building the computer Z1 in 1936, Konrad Zuse described in two patent applications for his future projects that machine instructions could be stored in the same storage used for data, i.e., the stored-program concept.
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
Cell, a shorthand for Cell Broadband Engine Architecture, [a] is a 64-bit multi-core microprocessor and microarchitecture that combines a general-purpose PowerPC core of modest performance with streamlined coprocessing elements [2] which greatly accelerate multimedia and vector processing applications, as well as many other forms of dedicated computation.
The SAP architecture serves as an example in Digital Computer Electronics for building and analyzing complex logical systems with digital electronics. Digital Computer Electronics successively develops three versions of this computer, designated as SAP-1, SAP-2, and SAP-3. Each of the last two build upon the immediate previous version by adding ...

He noted that "very smart people" had to go down the "dead ends" of mechanical computers and decimal computing before reaching a scalable solution—namely, the electronic, binary computer with a von Neumann architecture. The book also covers more recent developments, including topics like floating point math, operating systems, and ASCII.
