FUNCTION OF EACH BLOCK
MCORE : MUCAP Core
MUCAP Core is a 20-bit fixed point DSP core. This core operates MOVE, BRANCH,
INTERRUPT, ADDRESSING and ARITHMETIC operations.
CLKGM : Clock Generation Module
This module generates internal and external clock. two type of clocks are generated external
clocks and clock from external crystal oscillator.
ADIF
: Audio Interface Module
This module is an interface of input/output serial audio data to external.
2-channels of input port, and 3-channel of output port.
2-audio data input registers and 6-output registers ( 20-bit ).
HSTIF
: Host Interface Module
This module transfers asynchronous serial data to host CPU, which has input data register
and output data register(20-bit).
GP
: General Port Module
This module has a 8-bit direction register and 8-bit data register. Each port is independent as
a 1pin input/output general port(total 8pins).
EXMIF
: External Memory Interface Module
This module reads and writes data to external memory(SRAM), which has 3-byte data read/
write mode and 1word(20bit) data read/write mode.
This module uses in-service-register in order to read and write 3-byte data.
EMUIF
: Emulator Interface Module
This module is used for in circuit emulation.
LOG
: LOG Module
This module has registers to refer to table data for the operation of logarithmic functions.
MEM
: Memory Module
This module restores data and programs.
