DSPs: New TI DSP with EMAC now 100% code compatible with TMS320C6000


Houston, Tex. — The TMS320C6743 digital signal processor (DSP) from Texas Instruments (TI) is a low-power DSP that couples the high precision and wide dynamic range of TI's floating-point TMS320C67x+ core with the higher system performance of TI's fixed-point TMS320C64x+ core.

According to the company, the C6743 is the industry's lowest-cost networked DSP and combines the ease-of-use and precision of floating-point programming with the connectivity and lower-cost options of fixed-point devices.

Based on the TMS320C674x core, the C6743 is object code compatible with all TMS320C6000 devices so developers can easily design a broad range of energy-efficient products by leveraging existing software code.

The new DSP integrates multiple connectivity options, such as an Ethernet MAC (EMAC) and multimedia card/secure digital (MMC/SD) peripherals, and is targeted for applications such as audio conferencing, power protection systems, industrial monitoring and test and measurement products such as oscilloscopes .

C6743 DSP combines the fixed-point C64x+ instruction set and the floating-point C67x+ instruction set to provide higher fixed-point performance and single-precision/double-precision floating-point for wider dynamic range in a single device.

The new DSP is 100 percent upward code compatible with devices based on the C6000 fixed- and floating-point cores so developers can get to market faster. It is scalable and pin-to-pin compatible with C674x and TI's OMAP-L137 low-power devices allow for the ability to expand an entire product portfolio ranging from low- and high-end designs using the same hardware and software platform.

The C6743 offers a wide range of connectivity options with an integrated EMAC and MMC/SD for designs that require high data transfer or Internet access, which also helps reduce cost by eliminating the need to purchase separate components to add network or wireless connectivity.

It has an efficient EDMA 3.0 engine for higher system performance and better debug with exception handling and cache coherency visibility.

192 KB of on-chip memory saves both power and cost by removing the need for external memory.

Low power consumption with 490mW total power and 60mW in standby mode gives developers the ability to lower heat dissipation and increase battery life depending on use case scenarios

The TMDX320C6743 DSP is available for sampling and is priced at USD $7.85 for quantities of 1,000 units. To jumpstart designs, developers can use the OMAP-L1x/C674x Starter Kit, TMDXOSKL137BET, which is priced at USD $395, includes a board-specific Code Composer Studio IDE and supports DSP/BIOS kernels.

TI also provides complementary power management and analog signal chain solutions, including high-efficiency DC/DC converters, LDOs, battery charger ICs, ADCs, DACs and touch screen controllers.
