[gem5-dev] Change in gem5/gem5[develop]: cpu: Adding GUPSGen ClockedObject.
Mahyar Samani has submitted this change. ( https://gem5-review.googlesource.com/c/public/gem5/+/47439 ) Change subject: cpu: Adding GUPSGen ClockedObject. .. cpu: Adding GUPSGen ClockedObject. This patch adds the code base to implement GUPSGen which is a ClockedObject that creates read/write requests to the memory to update elements in an array. The choosing of elements in the array follow a random distribution. Each element is read from and return as GUPSGen implements a key-value store program. Specifications are found in HPCC website from RandomAccess benchmark. link below. https://icl.cs.utk.edu/projectsfiles/hpcc/RandomAccess/ Change-Id: I5c07f230bee317fff2cceec04d15d0218e8ede9a Reviewed-on: https://gem5-review.googlesource.com/c/public/gem5/+/47439 Reviewed-by: Jason Lowe-Power Reviewed-by: Bobby R.
