What is bus in DSP?
The main buses (program memory bus and data memory bus) are also accessible from outside the chip, providing an additional interface to off-chip memory and peripherals. However, all DSPs can interface with external converters through serial or parallel ports.
What are the different buses of TMS320C54x processor and list their functions?
1.1 TMS320C54x Overview It combines an advanced modified Harvard architecture (with one program memory bus, three data memory buses, and four address buses), a CPU with application- specific hardware logic, on-chip memory, on-chip peripherals, and a highly specialized instruction set.
How many accumulators are present in TMS320C54xx processor?
The central processing unit (CPU) of TMS320C54xx processors consists of a 40- bit arithmetic logic unit (ALU), two 40-bit accumulators, a barrel shifter, a 17×17 multiplier, a 40-bit adder, data address generation logic (DAGEN) with its own arithmetic unit, and program address generation logic (PAGEN).
Which architecture is followed in TMS320C54xx processor?
TMS320C54xx processors have Harvard architecture and are 16 bit fixed point processors. instruction execution with which 6 instructions can be active at a given time.
What is built in DSP?
A DSP is a processor dedicated to number-crunching digital signals like audio. They’re designed to perform mathematical functions like addition and subtraction at high speed with minimal energy consumption. If a device is processing audio, it’s nearly guaranteed to have a built-in DSP.
What is TMS in DSP?
Texas Instruments TMS320 is a blanket name for a series of digital signal processors (DSPs) from Texas Instruments. The TMS32010 featured a fast multiply-and-accumulate operation useful in both DSP applications as well as transformations used in computer graphics.
How many bits are allotted to the buses have in tms320c54xx processor?
The performance of a processor gets enhanced with the provision of multiple buses to provide simultaneous access to various parts of memory or peripherals. The 54xx architecture is built around four pairs of 16-bit buses with each pair consisting of an address bus and a data bus.
What is a bus cycle?
The bus cycle is the cycle or time required to make a single read or write transaction between the cpu and an external device such as external memory. The machine cycle is the amount of cycles needed to do either a fetch, read or write operation.
