Embodiment Construction
[0044] figure 1 A dual scalar / vector datapath processor in accordance with a preferred embodiment of the present invention is described. The processor 100 includes separate L1 instruction register (L1I) 121 and L1 data register (L1D) 123 . Processor 100 includes a combined level two instruction / data cache (L2) 130, which holds both instructions and data. figure 1 The connection (bus 142 ) between the L1 instruction register 121 and the L2 combined instruction / data register 130 is illustrated. figure 1 The connection between the L1 data cache 123 and the L2 combined instruction / data cache 130 (bus 145) is illustrated. In a preferred embodiment of the processor 100 , the L2 combined I / D cache 130 stores both instructions to back up the L1 Irreg 121 and stores data to back up the L1 data cache 123 . In a preferred embodiment, the two-level combined instruction / data cache 130 is further implemented with known but figure 1 connection to higher-level cache and / or main memory in ...
