General Description Features. The 74F673A contains a 16-bit serial-in, serial-out shift Serial-to-parallel converter register and a 16-bit Parallel-Out storage register. A single 16-bit serial I/O shift register pin serves either as an input for serial entry or as a 16-bit parallel-out storage register. 3-STATE serial output.
This paper is the first work to perform a rigorous evaluation of bit-serial vs. bit-parallel in-situ processing-in-SRAM. Our results show that both approaches have similar area overheads. For 32-bit arithmetic operations, BS-VRAM improves throughput by 1.3–5.0× compared to BP-VRAM, while BP-VRAM improves latency by 3.0–23.0× compared to BS-VRAM.
SN74LS647 parallel-in/ serial-out 16-bit shift register, synchronous load - example; The SN74ALS166 shown above is the closest match of an actual part to the previous parallel-in/ serial out shifter figures. Let us note the minor changes to our figure above. First of all, there are 8-stages.
The 'LS674 is a 16-bit parallel-in, serial-out shift register. A three-state input/output (SER/Q15) port provides access for entering a serial data or reading the shift-register word in a recirculating loop. The device has four basic modes of operation: Hold (do nothing)
16 de oct. de 2018 · IC 74673 16-bit serial-in serial-out shift register with output storage registers. IC 74674 16-bit parallel-in serial-out shift register with three-state outputs. In these ICs, mostly used are. 74HC595 Serial-In-Parallel-Out shift register; 74HC165 Parallel-In-Serial-Out shift register; 74HC 194 4-bit bidirectional universal shift register
Serial-in, serial-out shift registers delay data by one clock time for each stage. They will store a bit of data for each register. A serial-in, serial-out shift register may be one to 64 bits in length, longer if registers or packages are cascaded. Below is a single stage shift register receiving data which is not synchronized to the register ...
74F676 16-bit Serial/parallel-in, Serial-out Shift Register . The F676 contains 16 flip-flops with provision for synchronous parallel or serial entry and serial output When the Mode (M) input is HIGH information present on the parallel data P15) inputs is entered on the falling edge of the Clock Pulse.
