The TMS320 architecture has been around for a while so a number of product variants have developed. The product codes used by Texas Instruments after the first TMS32010 processor have involved a series of processor named "TMS320Cabcd", where a is the main series, b the generation and cd is some custom number for a minor sub-variant.
Blackfin is a family of 16-/32-bit microprocessors developed, manufactured and marketed by Analog Devices.The processors have built-in, fixed-point digital signal processor (DSP) functionality performed by 16-bit multiply–accumulates (MACs), accompanied on-chip by a microcontroller. [1]
Digital signal processor (DSP) variants [ edit ] Several variants with an additional 16-bit digital signal processor (DSP) (for example for MP3 or Vorbis coding/decoding) with up to 675 million instructions per second (MIPS) [ 46 ] and integrated USB 2.0 interface [ 47 ] or as intellectual property [ 48 ] exist.
Being a Modified Harvard architecture processor, the 56k has three memory spaces+buses (and on-chip memory banks in some of the models): a program memory space/bus and two data memory space/bus. [7] The stack area is allocated in a separate address space, which is called "Stack Memory Space", [ 8 ] distinct from the main memory address space. [ 9 ]
When multiple, heterogeneous cores are included in the device (e.g. DM644x), DSP/BIOS Link drivers run on both the ARM processor and the DSP to provide communication between the two. A number of operating systems for the DaVinci ARM and support DaVinci and the DSP/BIOS Link drivers: FreeBSD; Linux kernel; Mentor Graphics Nucleus PLUS RTOS
The BeagleBoard-X15 [36] [37] is based on the TI Sitara AM5728 processor with two ARM Cortex-A15 cores running at 1.5 GHz, two ARM Cortex-M4 cores running at 212 MHz and two TI C66x DSP cores running at 700 MHz. [38] The processor provides USB 3.0 support and has a PowerVR dual-core SGX544 GPU running at 532 MHz.
The processor can also be programmed through USB from a Windows or Linux host, using the USB "Device Firmware Update" protocols. Atmel ships proprietary (source code included but distribution restricted) example programs and a USB protocol stack with the device.
Die of Motorola DSP96002.. The Motorola 96XXX (aka 96000, 96K) is a family of digital signal processor (DSP) chips produced by Motorola.They are based on the earlier Motorola 56000 and remain software compatible with them, but have been updated to a full single-precision (32-bit) floating point implementation that is compliant with the IEEE 754-1985 standard.
