Based on the key performance indicator value, data blocks generated by a producer component may be scaled down to reduce power and/or bandwidth consumption when being compressed according to a lossless compression module. The compressed data blocks are then stored in a memory component along with metadata that signals the scal- ing factor used prior to compression. Consumer components later retrieving the compressed data blocks from the memory component may decompress the 0 data blocks and upscale, if required, based on the scaling factor signaled by the metadata. 1215 1245 Increase scale settings of engine to default scale level N Monitor key performance indicator (rKPI\") Receive scaled down data/frame from engine and compress using lossless compression methodology Apply predetermined scaling factor(s) • ( Return ) W O 20 18/ 19 48 16 Al 1225 Raceme scaled down data/frame from engine and compress using lossless compreceion methodology FIG. 12 [Continued on next page] WO 2018/194816 Al O II TR), OAPI (BF, BJ, CF, CG, CI, CM, GA, GN, GQ, GW, KM, ML, MR, NE, SN, TD, TG).
