The ADSP-2191MBSTZ-140 is an embedded digital signal processor (DSP) in the ADSP-219x family. It is designed for applications such as industrial control, medical imaging, speech and acoustic signal processing, video processing and telecommunications. This DSP is designed to offer high-performance signal processing capabilities with low power consumption. It features a 32-bit microprocessor core with 16K words of on-chip static RAM and 4K words of configurable on-chip ROM.

The ADSP-2191MBSTZ-140 offers several features that make it well-suited for embedded applications. It has an on-chip program sequencer to allow simplified software development. It supports standard buses such as Enhanced Universal Bus (EUB) and Serial Peripheral Interface (SPI). Additionally, its low power consumption, multiple serial ports and DMA support make it ideal for mobile applications.

The working principle of the ADSP-2191MBSTZ-140 is that it executes instructions from its local memory in a precise sequence of steps. Its program is stored in its local memory, where it is loaded and executed when a specific command is initiated. This DSP can accept instructions from external devices as well as execute instructions stored in its program memory. Furthermore, it can also access registers and perform operations such as address computation, register addressing and data manipulation.

Internally, the ADSP-2191MBSTZ-140 consists of two 16-bit data buses and a 32-bit address bus. The two 16-bit data buses are used to transfer data to and from memory and other devices. The 32-bit address bus is used to address memory and other devices. The internal bus structure of this DSP supports up to 16 data transfers and eight simultaneous memory accesses.

The ADSP-2191MBSTZ-140 supports several instructions sets such as Move, Add, Subtract, Multiply and Divide. It also supports multi-cycle instructions such as Indirect Addressing, Block Move and Block Test, and can operate on 16-bit, 32-bit and 64-bit data words. Additionally, it also supports several programming languages such as assembly language, C and BASIC.

The ADSP-2191MBSTZ-140 includes an on-chip program sequencer that simplifies software development. It allows the execution of instructions from external devices as well as instructions stored in program memory. It also allows the execution of multiple instructions concurrently, with the ability to suspend and resume instruction execution. Furthermore, it supports interrupts to external devices, enabling greater flexibility and enhanced system responsiveness.

The ADSP-2191MBSTZ-140 is designed for use in embedded applications where power consumption and system cost are important considerations. Its low power consumption and its high performance make it well-suited for many signal processing applications. Additionally, its support for various programming languages, multi-cycle instructions and interrupts make it easy to develop embedded software applications.
