It is composed By a private L1 Instruction cache, SCM based with small footprint and  2 way set associative, followed by a central L2 instruction cache, shared among the cores, and tuned for high capacity. The benefit of this IP is to alleviate the timing pressure on the prcessor fetch interface.\n\n# Run\nIn the SIM folder source the compile script.\n\n```\nsource ./compile.csh\n```\n\nCaches are by default disabled. To control them, a icache control unit is required.\nTemporarely, user can enable it forcing the enable req from simulator command line using tcl script:\n\n\nTo enable the ICACHES without L1 to L1.5 prefetch feature\n```\nsource enable_icache_no_prefetch.tcl\n```\n\nSelf checking logic will check every transaction made.\n\n# Block diagram\n![HierIcache](./DOC/HierIcache.png)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulp-platform%2Fhier-icache","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpulp-platform%2Fhier-icache","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpulp-platform%2Fhier-icache/lists"}
