Floating-point supportive pipeline for emulated shared memory architectures

Matti Forsell (Inventor)

Research output: PatentPatent

Abstract

A processor architecture arrangement for emulated shared memory (ESM) architectures, comprising a number of multi-threaded processors each provided with interleaved inter-thread pipeline (400) and a plurality of functional units (402, 402b, 402c, 404, 404b, 404c) for carrying out arithmetic and logical operations on data, wherein the pipeline (400) comprises at least two operatively parallel pipeline branches (414, 416), first pipeline branch (414) comprising a first sub-group of said plurality of functional units (402, 402b, 402c), such as ALUs (arithmetic logic unit), arranged for carrying out integer operations, and second pipeline branch (416) comprising a second, non-overlapping sub-group of said plurality of functional units (404, 404b, 404c), such as FPUs (floating point unit), arranged for carrying out floating point operations, and further wherein one or more of the functional units (404b) of at least said second sub-group arranged for floating point operations are located operatively in parallel with the memory access segment (412, 412a) of the pipeline (400).
