Abstract
A vector processor provides a data path divided into smaller slices of data, with each slice processed in parallel with the other slices. Furthermore, an execution unit provides smaller arithmetic and functional units chained together to execute more complex microprocessor instructions requiring multiple cycles by sharing single-cycle operations, thereby reducing both costs and size of the microprocessor. One embodiment handles 288-bit data widths using 36-bit data path slices. Another embodiment executes integer multiply and multiply-and-accumulate and floating point add/subtract and multiply operations using single-cycle arithmetic logic units. Other embodiments support 8-bit, 9-bit, 16-bit, and 32-bit integer data types and 32-bit floating data types.
