The ADSP-21msp58 and ADSP-21msp59 Mixed-Signal Processors (MSProcessor® DSPs) are fully integrated, single-chip DSPs complete with a high performance analog front end. The ADSP-21msp58/59 Family is optimized for voice band applications such as Speech Compression, Speech Processing, Speech Recognition, Text-to Speech, and Speech-to-Text conversion.
The ADSP-21msp58/59 combines the ADSP-2100 base architecture (three computation units, data address generators, and program sequencer) with two serial ports, a host interface port, an analog front end, a programmable timer, extensive interrupt capability, and on-chip program and data memory.
The ADSP-21msp58 provides 2K words (24-bit) of program RAM and 2K words (16-bit) of data memory. The ADSP- 21msp59 provides an additional 4K words (24-bit) of program ROM. The ADSP-21msp58/59 integrates a high performance analog codec based on a single chip, voice band codec, the AD28msp02. Powerdown circuitry is also provided to meet the low power needs of battery operated portable equipment. The ADSP-21msp58/59 is available in a 100-pin TQFP package (thin quad flat package).
In addition, the ADSP-21msp58/59 supports new instructions, which include bit manipulationsbit set, bit clear, bit toggle, bit testnew ALU constants, new multiplication instruction (x squared), biased rounding, and global interrupt masking.
