Working Principle of PDSH15-5,08

The PDSH15-5,08 is a digital signal processor (DSP) based on a reduced instruction set computer (RISC) architecture. Its main processor operates at a clock speed of 66 MHz with a 16-bit instruction set. This provides high processing performance for applications requiring high data throughput. The processor consists of a 32-bit accumulator, two 16-bit instruction pointers, a 16-bit program counter, 15-bit arithmetic logic unit, 32-bit address bus, and multiplexed data bus.

The processor performs eight basic instructions: RRC (Rotate Right through Carry), RLC (Rotate Left through Carry), MOVA R5, z (Move Register five into Address register), Memory Access, Load Halfword, Clear Memory, Memory Access with Immediate Data (DataA), and Load Word. It also supports interrupts, serial communications, and direct memory access (DMA).

The PDSH15-5,08 has an integrated memory controller for controlling external RAM and Flash memory. It can also be combined with external FPGAs or ASICs for custom signal processing tasks such as digital filtering or noise reduction. It has on-chip support for communication protocols such as USB, I2C, SPI, and RS-232, as well as support for external Ethernet. The processor also supports multiple clock speeds, delivering performance up to 66 MHz.
