Instruction and Data Cache
Each addressable memory space outside the L1 memory can be The ADSP-2156x processors also include a traditional instruc- accessed either directly or via cache. tion cache (I-cache) and two data caches (D-cache) The memory map in Table 2 gives the L1 memory address space (PM/DM caches) with parity support for all caches. These and shows multiple L1 memory blocks offering a configurable caches support one instruction access and two data accesses mix of SRAM and cache. over the DM and PM buses, per CCLK cycle. The cache control- lers automatically manage the configured L1 memory. The
L1 Master and Slave Ports
system can configure part of the L1 memory for automatic man- The SHARC+ core has two master/slave ports to and from the agement by the cache controllers. The sizes of these caches are system fabric. One master port fetches instructions. The second independently configurable from 0 Kb to a maximum of master port drives data to the system world. Slave port 1 1024 Kb each. The memory not managed by the cache control- together with slave port 2 (MDMA) run conflict free access to lers is directly addressable by the processors. The controllers the individual memory blocks. For the slave port addresses, ensure the data coherence between the two data caches. The refer to the L1 memory address map in Table 2. caches provide user-controllable features such as full and partial locking, range-bound invalidation, and flushing.
L1 On-Chip Memory Bandwidth System Event Controller (SEC) Input
The internal memory architecture allows programs to have four accesses at the same time to any of the four blocks, assuming no The output of the system event controller (SEC) controller is block conflicts. The total bandwidth is realized using both the forwarded to the core event controller (CEC) to respond DMD and PMD buses (2 × 64-bits CCLK speed and 2 × 32-bit directly to all unmasked system-based interrupts. The SEC also SYSCLK speed). supports nesting including various SEC interrupt channel Rev.
