Embedded Core Block RAM
There are two independent memory slices (labeled A and B) in the embedded core. Each memory slice has a
capacity of 4K words by 36 bits. These are in addition to the block RAMs found in the FPGA portion of the
ORSO82G5. Although the memory slices are in the embedded core part of the chip, they do not interact with the
rest of the embedded core circuits, but are standalone memories designed specically to increase RAM capacity in
the ORSO82G5 chip. They can be used by the soft IP cores implemented in the FPGA portion of the FPSC.
A block diagram of a memory slice is shown in Figure 45. Each memory slice is organized into two sections
(labeled SRAM A and SRAM B) and has one read port, one write port and four byte-write-enable (active-low) sig-
nals. Each byte has eight data bits and a control/parity bit. The control/parity bit responds to the same byte enable
(BYTEWN_x[x]) as it’s corresponding data. No special logic such as parity checking is performed on this bit by the
core. The read data from the memory is registered so that it works as a pipelined synchronous memory block. The
minimum timing specications are shown in Figure 46 and Figure 47. Signal names and functions are summarized
later in Table 12 and follow the general Series 4 naming conventions.
