Path in the library:

/Basic/Additional/Discrete/Simple Dual Port RAM

Description

Block Simple Dual Port RAM It simulates RAM that supports simultaneous read and write operations and has one output port for reading data.

Simple dual-port RAM is similar to dual-port RAM, but dual-port RAM has both a write output port and a read output port.

Reading and writing behavior

During a write operation, if a read operation occurs at the same address, old data appears at the output.

Ports

Input

# wr_din — entering data for recording
scalar

Details

The data that you write to the RAM memory location when the wr_en signal is true. The data type is determined by the Data type parameter.

Data types	`Float64` \| `Float32` \| `Float16` \| `Int8` \| `UInt8` \| `Int16` \| `UInt16` \| `Int32` \| `UInt32` \| `Int64` \| `UInt64` \| `Int128` \| `UInt128` \| `Bool` \| `Fixed-point`
Complex numbers support	Yes

# wr_addr — the address of the record
scalar

Details

The write address where you write data when the wr_en signal is true.

Data types	`UInt8` \| `UInt16` \| `UInt32` \| `UInt64` \| `UInt128` \| `Fixed-point`
Complex numbers support	No

# wr_en — recording resolution
scalar

Details

Recording permission.

If wr_en equal to true the RAM writes data to the memory location you specify.

Data types	`Bool`
Complex numbers support	No

# rd_addr — reading address
scalar

Details

The address from which you are reading the data.

Data types	`UInt8` \| `UInt16` \| `UInt32` \| `UInt64` \| `UInt128` \| `Fixed-point`
Complex numbers support	No

Output

# rd_dout — data output from the read address
scalar

Details

Output of data from the read address, rd_addr.

Data types	`Float32` \| `Float63` \| `int8` \| `Int16` \| `Int32` \| `Int64` \| `Uint8` \| `Uint16` \| `Uint32` \| `Uint64` \| `Bool` \| `Fixed-point`
Complex numbers support	No
