Filed:

Dec 9, 2019

Appl. No.:

16/708261

Inventors:

- Santa Clara CA, US
Andrew Kerr - San Francisco CA, US
John Tran - Denver CO, US
Ming Y. Siu - Santa Clara CA, US
Stuart Oberman - Sunnyvale CA, US

International Classification:

G06F 9/30

Abstract:

A method, computer readable medium, and processor are described herein for inline data inspection by using a decoder to decode a load instruction, including a signal to cause a circuit in a processor to indicate whether data loaded by a load instruction exceeds a threshold value. Moreover, an indication of whether data loaded by a load instruction exceeds a threshold value may be stored.

Abstract:

A method, computer readable medium, and system are disclosed for inline data inspection. The method includes the steps of receiving, by a load/store unit, a load instruction and obtaining, by an inspection circuit that is coupled to the load/store unit, data specified by the load instruction. Additional steps include determining that the data equals zero and transmitting the data and a predicate signal to the load/store unit, wherein the predicate signal indicates that the data equals zero. Alternative additional steps include computing a predicate value based on a comparison between the data and a threshold value and transmitting the data and the predicate value to the load/store unit, wherein the predicate value is asserted when the data is less than the threshold value and is negated when the data is not less than the threshold value.
