Embodiment Construction

[0031] One or more embodiments of the invention are described below. It should be noted that these and any other embodiments described below are exemplary and are intended to be illustrative of the invention, not limiting.

[0032]As noted above, various embodiments of the invention include systems and methods for processing data using an array of data processing units coupled together using variable precision interconnects. One embodiment includes an array of processing units with simple unit-to-unit interconnects that are fixed in width but support data with variable precision. Units receive input data on these links and also send results of operations on them. The operations performed by each unit may be fixed, or variable / programmable. Data is transferred between units only when the sender has new data available and the receiver requires new data. Additionally, asynchronous cells can be used to minimize power and improve performance.

[0033] In one embodiment, the var...

Abstract

Systems and methods for processing data using an array (11) of data processing elements (13) that are coupled together with a variable precision interconnect (14). One embodiment comprises data processing elements coupled by variable precision interconnects to form a row-column array (11). The interconnects (14) and / or data processing elements (13) may be synchronous or asynchronous. The data processing elements (13) may operate in a fixed manner, or they may be programmable, and selectable data processing elements (13) in the array may be bypassed. The interconnects (14) and data processing elements (13) may be configured to handle data in a digit-serial manner, with tags (25, 26) for each digit identifying whether the digit is the first and / or last digit in a data word. The data processing elements may be coupled to a system bus (54, 55) that enables communication of data between the data processing elements and external devices and allows control information to be communicated to and from the data processing elements.

Description

technical field [0001] The present invention relates generally to electronic logic circuits, and more particularly to systems and methods for processing variable precision data that uses tags to identify the position of numbers within data words. Background technique [0002] As computer technology has advanced, the amount of processing power and speed of computer systems has increased. The speed at which these systems can execute software programs has thus increased. However, despite these increases, there remains a continuing desire to make software programs perform faster. [0003] The need for speed is sometimes handled through hardware acceleration. Traditional processors reuse the same hardware for each instruction of a sequential program. Programs often contain critical code in which the same or similar parts of the software are executed many times relative to most other parts in the application program. To speed up the program, additional hardware is added to pro...
