ADSP-21566/21567/21569 SHARC PROCESSOR
The SHARC processor supports a modified Harvard architec- ture in combination with a hierarchical memory structure. L1 The SHARC processor integrates a SHARC+ SIMD core, L1 memories typically operate at the full processor speed with little memory crossbar, I-cache/D-cache controller, L1 memory or no latency. blocks, and the master/slave ports, as shown in Figure 2. The SHARC+ SIMD core block diagram is shown in Figure 3.

L1 Memory
The SRAM of the processor can be configured as a maximum of 160k words of 32-bit data, 320k words of 16-bit data, Figure 4 shows the ADSP-2156x memory map. The SHARC+ 106.7k words of 48-bit instructions (or 40-bit data), or combi- core has a tightly coupled 5 Mb L1 SRAM. The SHARC+ core nations of different word sizes up to 5 Mb. All of the memory can access code and data in a single cycle from this memory can be accessed as 8-bit, 16-bit, 32-bit, 48-bit, or 64-bit words. space. Support of a 16-bit floating-point storage format doubles the In the SHARC+ core private address space, the core has L1 amount of data that can be stored on chip. memory. Conversion between the 32-bit floating-point and 16-bit float- SHARC+ core memory-mapped register (CMMR) address ing-point formats is performed in a single instruction. Whereas space is 0x0000 0000 through 0x0003 FFFF in normal word each memory block can store combinations of code and data, (32-bit). Each block can be configured for different combina- accesses are most efficient when one block stores data using the tions of code and data storage. Of the 5 Mb SRAM, up to 1 Mb DM bus for transfers, and the other block stores instructions can be configured for data memory (DM), program memory and data using the PM bus for transfers. (PM), and instruction cache each. Each memory block supports Using the DM and PM buses, with each bus dedicated to a single-cycle, independent accesses by the core processor and I/O memory block, assures single-cycle execution with two data processor. The memory architecture, in combination with its transfers. In this case, the instruction must be available in the separate on-chip buses, allows two data transfers from the core cache. The system configuration is flexible, but a typical config- and one from the direct memory access (DMA) engine in a uration is 512 kb DM, 128 kb PM, and 128 kb of instruction single cycle.
