·SC-6X支持位速率的语音合成，符合质量范围和存储要求 ·14通道音乐或10通道伴有语音的音乐是可能的

at a glance:

• SC-6X supports speech synthesis in bit rates covering a range of quality and memory requirements.
• As many as 14 channels of music or 10 channels of music simultaneous with speech are possible.

The SC-6x DSP family targets speech- and music-synthesis applications. The Sensory speech algorithms support long-duration speech with data rates as low as 1 kbps using MX and the industry’s highest quality using CX. Six fixed-bit rates of CX, beginning at 3 kbps, and a variable range of MX bit rates are available to mix and match your quality and memory requirements. The SC-6x family supports 14-channel, polyphonic music and as many as 10 channels of music simultaneously with speech playback. These DSPs support three low-power modes, two timer interrupts, one DAC interrupt, and five general-purpose interrupts to improve battery life and response speed to button and keyboard presses. The SC-6x devices include 32 I/O lines to support speech and music synthesis and general-purpose product control with interactive interfaces.

Addressing and processing modes: The addressing modes are immediate, direct, indirect-with-postmodification, and three relative modes. The program-counter unit comprises the program counter, the data pointer, a buffer register, a code-protection write-only register, and a hardware-loop counter for strings and repeated-instruction loops. It provides addressing for program memory (onboard ROM) and includes a 16-bit arithmetic block for incrementing and loading addresses. The program-counter unit generates a ROM address as output.

Special instructions or integral-peripheral functions: The SC-6x processors offer instructions to facilitate filtering algorithms, such as FIR, FIRK, COR, and CORK. FIR is useful for adaptive filtering or applications in which coefficients come from an external source. COR instructions perform 16×16-bit multiplies and 48-bit accumulation in three clock cycles. Instructions are available to perform 16×16-bit multiplies and 32-bit accumulation in two clock cycles.

Development support: The RSC and SC-6x development-tool suite includes an in-circuit emulator with an integrated debugger and a C compiler. Quick T2SI allows text entry and generation of recognition sets, and Quick Synthesis and the SCT6000 tool provide “pushbutton” speech compression. A tool for integration of MIDI-format music in an SC-6x application includes a rich selection of music voices (instruments). Demonstration units and evaluation and prototyping tools, such as the Voice Extreme Toolkit, are available. Each kit includes required hardware and software, complete documentation, and numerous examples. Turnkey product-development and linguistics services are available directly through Sensory or through its worldwide network of third-party-development houses.
