DREAM® IC’s cover a wide range of sound synthesis and sound processing solutions, from low cost to high quality levels.
SAM5000 series ICs
The SAM5000 series is built around a new highly speed optimized 16-bit CPU (P16XT) and a configurable array of hardware accelerated 24-bit DSP cores (P24XT) enabling 56-bit MAC operations. With a sophisticated sample buffering system and a multi-channel Audio DMA operating in a multi-layer architecture, the SAM5000 series is capable of high performances for sound synthesis, audio processing and effects generation.
The new series supports a large variety of memory types: SLC NAND Flash, parallel or serial (Quad-SPI) NOR Flash, SRAM or DDR/SDR SDRAM.
A built-in 1kbit eFuse provides a plenty of irreversible One-Time-Programmable (OTP) bits for the storage of configuration parameters, decrypt keys and other security purposes while copy-protected sound banks and firmware are decrypted on-the-fly.
All members of the SAM5000 series also offer state-of-the-art communication interfaces such as USB 2.0 High Speed, 10-100Mbps Ethernet MAC and S/PDIF. Additionally, adaptive clocking schemes including phase synchronization to external audio clocks are supported.
Time-to-market cycles are significantly reduced by providing comprehensive development tools, libraries and software suites that are delivered on request.
